A flight of two Consolidated-Vultee B-36B Peacemaker strategic bombers. (LIFE Magazine)
13 February 1950: Two Consolidated-Vultee B-36B Peacemaker long-range strategic bombers of the 436th Bombardment Squadron (Heavy), 7th Bombardment Wing (Heavy), Strategic Air Command, departed Eielson Air Force Base (EIL), Fairbanks, Alaska, at 4:27 p.m., Alaska Standard Time (01:27 UTC), on a planned 24-hour nuclear strike training mission.
B-36B-15-CF 44-92075 was under the command of Captain Harold Leslie Barry, United States Air Force.¹ There were a total of seventeen men on board.
Also on board was a Mark 4 nuclear bomb.
The B-36s were flown to Alaska from Carswell Air Force Base, Fort Worth, Texas, by another crew. The surface air temperature at Eielson was -40 °F. (-40 °C.), so cold that if the bomber’s engines were shut down, they could not be restarted. Crews were exchanged and the airplane was serviced prior to takeoff for the training mission. In addition to the flight crew of fifteen, a Bomb Commander and a Weaponeer were aboard.
After departure, 44-92075 began the long climb toward 40,000 feet (12,192 meters). The flight proceeded along the Pacific Coast of North America toward the practice target city of San Francisco, California. The weather was poor and the bomber began to accumulate ice on the airframe and propellers.
About seven hours into the mission, three of the six radial engines began to lose power due to intake icing. Then the #1 engine, outboard on the left wing, caught fire and was shut down. A few minutes later, the #2 engine, the center position on the left wing, also caught fire and was shut down. The #3 engine lost power and its propeller was feathered to reduce drag. The bomber was now flying on only three engines, all on the right wing, and was losing altitude. When the #5 engine, center on the right wing, caught fire, the bomber had to be abandoned. It was decided to jettison the atomic bomb into the Pacific Ocean.

The Mark 4 did not have the plutonium “pit” installed, so a nuclear detonation was not possible. The conventional explosives would go off at a pre-set altitude and destroy the bomb and its components. This was a security measure to prevent a complete bomb from being recovered.
The bomb was released at 9,000 feet (2,743 meters), north-northwest of Princess Royal Island, off the northwest coast of British Columbia, Canada. It was fused to detonate 1,400 feet (427 meters) above the surface, and crewmen reported seeing a large explosion.

Flying over Princess Royal Island, Captain Barry ordered the crew to abandon the aircraft. He placed the B-36 on autopilot. Barry was the last man to leave 44-92075. Descending in his parachute, he saw the bomber circle the island once before being lost from sight.

Twelve of the crew survived. Five were missing and it is presumed that they landed in the water. Under the conditions, they could have survived only a short time. The survivors had all been rescued by 16 February.
It was assumed that 44-92075 had gone down in the Pacific Ocean.

On 20 August 1953, a Royal Canadian Air Force airplane discovered the wreck of the missing B-36 on a mountain on the east side of Kispiox Valley, near the confluence of the Kispiox and Skeena Rivers in northern British Columbia.
The U.S. Air Force made several attempts to reach the crash site, but it wasn’t until August 1954 that they succeeded. After recovering sensitive equipment from the wreckage, the bomber was destroyed by explosives.
Bomb, Mark 4. (Nuclear Weapons Archive)
The Mark 4 bomb was designed by the Los Alamos National Laboratory (LANL). It was a development of the World War II implosion-type Mark 3 “Fat Man.” The bomb was 10 feet, 8 inches (3.351 meters) long with a maximum diameter of 5 feet, 0 inches (1.524 meters). Its weight is estimated at 10,800–10,900 pounds (4,899–4,944 kilograms).
The core of the bomb was a spherical composite of plutonium and highly-enriched uranium. This was surrounded by approximately 5,500 pounds (2,495 kilograms) of high explosive “lenses”—very complex-shaped charges designed to focus the explosive force inward in a very precise manner. When detonated, the high explosive “imploded” the core, crushing it into a smaller, much more dense mass. This achieved a “critical mass” and a fission chain reaction resulted.
The Mark 4 was tested during Operation Ranger at the Nevada Test Site, Frenchman Flat, Nevada, between 27 January and 6 February 1951. Five bombs were dropped from a Boeing B-50 Superfortress of the 4925th Special Weapons Group from Kirtland Air Force Base in New Mexico. The first four bombs were dropped from a height of 19,700 feet (6,005 meters) above ground level (AGL) and detonated at 1,060–1,100 feet (323–335 meters) AGL. Shot Fox was dropped from 29,700 feet (9,053 meters) AGL and detonated at 1,435 feet (437 meters) AGL. (Ground level at Frenchman Flat is 3,140 feet (957 meters) above Sea Level).
Operation Ranger, Shot Able, 5:45 a.m., 27 January 1951. Mark 4 bomb with Type D pit, 1,060 foot (323 meters) air burst. Yield, 1 kiloton. This was the first nuclear test in the continental United States since Trinity, 16 July 1945.
The Mark 4 was produced with explosive yields ranging from 1 to 31 kilotons. 550 were built.
Consolidated-Vultee B-36B-15-CF Peacemaker 44-92075 was completed at Air Force Plant 4, Fort Worth, Texas, on 31 July 1949. It had been flown a total of 185 hours, 25 minutes.
The B-36B is 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 8 inches (14.224 meters). The wings’ leading edges were swept aft 15° 5′ 39″. Their angle of incidence was 3°, with -2° twist and 2° dihedral. The empty weight is 137,165 pounds (62,217 kilograms) and the maximum takeoff weight was 326,000 pounds (147,871 kilograms).
With a wing area of 4,772 square feet (443 square meters) and 21,000 horsepower, the B-36 could fly far higher than any jet fighter of the early 1950s.

The B-36B was powered by six air-cooled, supercharged and turbocharged 4,362.49 cubic-inch-displacement (71.488 liter) Pratt & Whitney Wasp Major B4 (R-4360-41) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. Each engine was equipped with two General Electric BH-1 turbochargers. The R-4360-41 had a Normal Power rating of 2,650 horsepower at 2,550 r.p.m. Its Takeoff/Military Power rating was 3,500 horsepower at 2,700 r.p.m., with water/alcohol injection. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-41 is 9 feet, 1.75 inches (2.788 meters) long, 4 feet, 6.00 inches (1.372 meters) in diameter, and weighs 3,567 pounds (1,618 kilograms).
The B-36B Peacemaker had a cruise speed of 193 knots (222 miles per hour/357 kilometers per hour) and a maximum speed of 338 knots (389 miles per hour/626 kilometers per hour) at 35,500 feet (10,820 meters). The service ceiling was 43,700 feet (13,320 meters) and its combat radius was 3,710 nautical miles (4,269 statute miles/6,871 kilometers). The maximum ferry range was 8,478 nautical miles (9,756 statute miles/15,709 kilometers).
The B-36 was defended by sixteen M24A-1 20 mm automatic cannons. Six retractable gun turrets each each had a pair of 20 mm cannon, with 600 rounds of ammunition per gun (400 r.p.g.for the nose guns). These turrets were remotely operated by gunners using optical sights. Two optically-sighted 20 mm guns were in the nose, and two more were in a tail turret, also remotely operated and aimed by radar.
In this photograph, two of the B-36’s retractable gun turrets are visible behind the cockpit, as well as the nose gun turret. The plexiglas “blister” just ahead and below the dorsal turrets is a gunner’s sighting station. The bomb bay doors are open. (Unattributed)
The B-36 was designed during World War II and nuclear weapons were unknown to the Consolidate-Vultee Aircraft Corporation engineers. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in the four-section bomb bay. It could carry two 43,600 pound (19,777 kilogram) T-12 Cloudmakers, a conventional explosive earth-penetrating bomb. When armed with nuclear weapons, the B-36 could carry several Mk.15 thermonuclear bombs. By combining the bomb bays, one Mk.17 25-megaton thermonuclear bomb could be carried.
Between 1946 and 1954, 384 B-36 Peacemakers were built by Convair. 73 of these were B-36Bs, the last of which were delivered to the Air Force in September 1950. By 1952, 64 B-36Bs had been upgraded to B-36Ds.
The B-36 Peacemaker was never used in combat. Only four still exist.
¹ Captain Barry was killed along with other 11 crewmen, 27 April 1951, when the B-36D-25-CF on which he was acting as co-pilot, 49-2658, crashed following a mid-air collision with a North American F-51-25-NT Mustang, 44-84973, 50 miles (80 kilometers) northeast of Oklahoma, City, Oklahoma, U.S.A. The Mustang’s pilot was also killed.
Brigadier General Charles E. Yeager, United States Air Force
Brigadier General Charles Elwood Yeager, United States Air Force, was born at Myra, Lincoln County, West Virginia, 13 February 1923. He was the second of five children of Albert Halley Yeager, a gas field driller, and Susan Florence Sizemore Yeager. He attended Hamlin High School, at Hamlin, West Virginia, graduating in 1940.
Chuck Yeager enlisted as a private, Air Corps, United States Army, 12 September 1941, at Fort Thomas, Newport, Kentucky. He was 5 feet, 8 inches tall (1.73 meters) and weighed 133 pounds (60 kilograms), with brown hair and blue eyes. He was assigned service number 15067845. Initially an aircraft mechanic, he soon applied for flight training. Private Yeager was accepted into the “flying sergeant” program.

Sergeant Yeager completed flight training at Yuma, Arizona, and on 10 March 1943, he was given a warrant as a Flight Officer, Air Corps, Army of the United States.
Assigned to the 363rd Fighter Squadron at Tonopah, Nevada, Flight Officer Yeager completed advanced training as a fighter pilot in the Bell P-39 Airacobra.
On 23 October 1943, while practicing tactics against a formation of Consolidated B-24 Liberator bombers, the engine of Yeager’s P-39 exploded. He wrote,
I was indicating about 400 mph when there was a roaring explosion in the back. Fire came out from under my seat and the airplane flew apart in different directions. I jettisoned the door and stuck my head out, and the prop wash seemed to stretch my neck three feet. I jumped for it. When the chute opened, I was knocked unconscious. . . I was moaning and groaning in a damned hospital bed. My back was fractured and it hurt like hell.

When the 363rd deployed to England in November 1943, he transitioned to the North American Aviation P-51B Mustang. He named his P-51B-5-NA, 43-6762, Glamourus Glen, after his girlfriend. The airplane carried the squadron identification markings B6 Y on its fuselage. On 4 March 1944, he shot down an enemy Messerschmitt Bf-109G.
On his eighth combat mission, the following day, Yeager was himself shot down east of Bourdeaux, France, by Focke-Wulf Fw 190A 4 flown by Unteroffizier Irmfried Klotz.
. . . The world exploded and I ducked to protect my face with my hands, and when I looked a second later, my engine was on fire, and there was a gaping hole in my wingtip. The airplane began to spin. It happened so fast, there was no time to panic. I knew I was going down; I was barely able to unfasten my safety belt and crawl over the seat before my burning P-51 began to snap and roll, heading for the ground. I just fell out of the cockpit when the plane turned upside down—my canopy was shot away.

Yeager was slightly wounded. His Mustang was destroyed. Over the next few months he evaded enemy soldiers and escaped through France and Spain, returning to England in May 1944. He returned to combat with a new P-51D-5-NA Mustang, 44-13897, which he named Glamorous Glenn II.¹ He later flew Glamorous Glen III, P-51D-15-NA Mustang, 44-14888.²

Flight Officer Yeager was commissioned as a 2nd lieutenant, Air Corps, Army of the United States, 6 July 1944. A few months later, 24 October 1944, he was promoted to the rank of captain, A.U.S. Between 4 March and 27 November 1944, Captain Yeager was officially credited with 11.5 enemy aircraft destroyed during 67 combat missions.

During World War II, Captain Yeager had been awarded the Silver Star with one oak leaf cluster (two awards); Distinguished Flying Cross; Bronze Star Medal with “V” (for valor); Air Medal with 6 oak leaf clusters (7 awards); and the Purple Heart.
With the end of the War in Europe approaching, Yeager was rotated back to the United States.
Captain Yeager married Miss Glennis Faye Dickhouse of Oroville, California, 26 February 1945, at at the Yeager family home in Hamlin, West Virginia. The double-ring ceremony was presided over by Rev. Mr. W. A. DeBar of the Trinity Methodist Church. “The pretty brunette was attired in a light aqua crepe dress of street length. Her accessories were black and her corsage was fashioned of yellow rosebuds.”
On 10 February 1947, Captain Yeager received a commission as a second lieutenant, Air Corps, United States Army, with date of rank retroactive to 6 July 1944 (the date of his A.U.S. commission). He was promoted to first lieutenant on 6 July 1947. (These were permanent Regular Army ranks. Yeager continued to serve in the temporary rank of captain.) When the United States Air Force was established as a separate military service, 18 September 1947, Yeager became an Air Force officer.
Captain Chuck Yeager, U.S. Air Force
Captain Yeager was assigned to the six-month test pilot school at Wright Field, Dayton, Ohio. He took part in several test projects, including the Lockheed P-80 Shooting Star and Republic P-84 Thunderjet. He also evaluated the German and Japanese fighter aircraft brought back to the United States after the war. Captain Yeager was then selected by Colonel Albert Boyd to fly the experimental Bell XS-1 rocket plane at Muroc Field in the high desert of southern California.

After a series of gliding and powered flights, on 14 October 1947, Captain Yeager and the XS-1 were dropped from a modified B-29 Superfortress at an altitude of 20,000 feet (6,048 meters). (Yeager had named his new rocket plane Glamorous Glennis.) Starting the 4-chambered Reaction Motors rocket engine, Yeager accelerated to Mach 1.06 at 42,000 feet. He had “broken” the Sound Barrier.
Yeager made more than 40 flights in the X-1 over the next two years, exceeding 1,000 miles per hour (1,610 kilometers per hour) and 70,000 feet (21,336 meters). He was awarded the Mackay and Collier Trophies in 1948. In 1949, the Fédération Aéronautique Internationale awarded its Gold Medal to Captain Yeager. General Yeager’s gold medal is in the collection of the Smithsonian Institution National Air and Space Museum, along with the Bell X-1 rocket plane, Glamorous Glennis.
The X-1 was followed by the Bell X-1A. On 12 December 1953, Major Yeager flew the new rocket plane to 1,650 miles per hour (2,655 kilometers per hour), Mach 2.44, at 74,700 feet (22,769 meters).
After the rocket engine was shut down, the X-1A tumbled out of control—”divergent in three axes” in test pilot speak—and fell out of the sky. It dropped nearly 50,000 feet (15,240 meters) in 70 seconds. Yeager was exposed to accelerations of +8 to -1.5 g’s. The motion was so violent that Yeager cracked the rocket plane’s canopy with his flight helmet.
Yeager was finally able to recover by 30,000 feet (9,144 meters) and landed safely at Edwards Air Force Base.
Yeager later remarked that if the X-1A had an ejection seat he would have used it.
Bell Aircraft Corporation engineers had warned Yeager not to exceed Mach 2.3.

Yeager attended the Air War College at Maxwell AFB, Montgomery, Alabama, graduating in June 1961.
On 23 July 1962, Colonel Yeager returned to Edwards Air Force Base to become commandant of the Aerospace Research Pilot School.

The Aerospace Research Pilots School trained all of the U.S. military’s astronaut candidates. One of the training aircraft was the Aerospace Trainer (AST), a highly-modifies Lockheed NF-104A Starfighter. The AST was equipped with a rocket engine and a reaction control system to provide pitch, roll and yaw control when at very high altitudes where the normal aircraft flight controls could not function.

On 10 December 1963, Colonel Yeager was flying an AST, 56-762, on a zoom climb profile, aimingg for an altitude record at approximately 120,000 feet ( meters). He reached only 108,000 feet (32,918 meters) however. On reentry, the AST’s pitch angle was incorrect and its engine would not restart. The airplane went into a spin.
Yeager rode the out-of-control airplane down 80,000 feet (24,384 meters) before ejecting.
The data recorder would later indicate that the airplane made fourteen flat spins from 104,000 until impact on the desert floor. I stayed with it through thirteen of those spins before I punched out. I hated losing an expensive airplane, but I couldn’t think of anything else to do. . . I went ahead and punched out. . . .

Brigadier General Yeager made his final flight as an active duty Air Force pilot in a McDonnell Douglas F-4E Phantom II at Edward Air Force Base, 28 February 1975. During his career, General Yeager flew 180 different aircraft types and accumulated 10,131.6 flight hours. He retired the following day, 1 March 1975, after 12,222 days of service.
Chuck Yeager’s popularity skyrocketed following the publication of Tom Wolfe’s book, The Right Stuff, in 1979, and the release of The Ladd Company’s movie which was based on it. (Yeager had a “cameo” appearance in the film.) He became a spokesperson for AC Delco and the Northrop Corporation’s F-20 Tigershark lightweight fighter prototype. In 1986 and 1988, he drove the pace car at the Indianapolis 500. Yeager co-wrote an autobiography, Yeager, with Leo Janos, published in 1985, and followed in 1988 with Press On!, co-authored by Charles Leerhsen.
In 1986, President Ronald Reagan appointed General Yeager to the Rogers Commission investigating the Challenger Disaster.
Glennis Yeager passed away 22 December 1990 at Travis Air Force Base, Sacramento, California.
TDiA was present at Edwards Air Force Base, 14 October 1997, on the 50th Anniversary of Yeager’s flight breaking the sound barrier. Flying in the forward cockpit of a McDonnell Douglas F-15D Eagle, with co-pilot Lieutenant Colonel Troy Fontaine and wingman Bob Hoover in a General Dynamics F-16 chase plane, Yeager again left a sonic boom in his path as he flew over the high desert.
On 22 August 2003, Chuck Yeager married Ms. Victoria Scott D’Angelo in a civil ceremony at Incline Village, Nevada.
Brigadier General Charles Elwood Yeager, United States Air Force (Retired) died at a hospital in Los Angeles, California, 7 December 2020, at the age of 97 years. His remains are buried at the Lincoln Memorial Cemetery, Myra, West Virginia.

MEDEVAC FROM THE FOG – SS STEEL EXECUTIVE
By Sean M. Cross, CAPT, USCG (retired)
“Lewis had to make what he considered to be one of the most crucial decisions of his life. Peering at the fog below him, he remembers asking himself a question to plunge or not to plunge…”
TODAY IN COAST GUARD AVIATION HISTORY – 12 FEBRUARY 1971: an HH-3F #1473 assigned to Air Station San Diego, CA and crewed by LCDR Paul R. Lewis (AC), LT Joseph O. Fullmer (CP), ASM3 Larry E. Farmer (FM), AT3 Charles Desimone (AV) and HM3 Richard M. McCollough (AMS) launched in response to an injured or ill “seaman in need of an operation” ¹ from the 492-foot freighter STEEL EXECUTIVE, approximately 220 miles south of San Diego. The WWII-era Type C3-class cargo ship owned by Isthmian Lines, Inc. of New York was on an extended trip from Saigon, South Vietnam to New York City via the Panama Canal with stops in Astoria, OR and various east coast ports. They departed Saigon on 29 January 1971 and on 12 February were southbound for the Panama Canal.² After requesting assistance, the ship reversed course back toward San Diego to reduce transit distance for the helicopter. This is their story.

Friday afternoon at around 4:00 PM, Rescue Coordination Center Long Beach launched the off-going Air Station San Diego HH-3F duty crew on a long range medical evacuation or MEDEVAC. The maintenance crew had to stop downtown vehicle traffic so that #1473 could taxi from the unit’s waterfront location across Harbor Drive to Lindberg Field in order to utilize the runway for a running takeoff – as the aircraft could not get airborne from a hover with a maximum fuel load.³ According to LCDR Lewis, taking off “out of San Diego, it was a clear afternoon,” ⁴ but the sun was lowering in the sky with official sunset at 5:31 PM.

During WWII these ships stood the test as cargo vessels and transports and after the war as cargo liners sold under Merchant Sales Act of 1946. These ships were widely used by U.S. and Foreign Steamship Companies into the 1970s.
After two hours of night overwater navigation and using a combination of radio direction finding, helicopter radar, and guidance from the STEEL EXECUTIVE, #1473 arrived in the vessel’s vicinity, but was unable to make visual contact through the dense fog which extended from the surface to about 700 feet above the water.
Flight mechanic Larry Farmer described the scene, “We flew over the estimated position at 1,500 feet and it was beautiful, you could see stars clear to either horizon, but glancing down – it looked like a huge layer of thick cotton blanketing the water below us.” ⁵

With visibility less than 1/8 mile, the helicopter directed the vessel to turn on all available topside lighting and dropped two MK-58 marine location markers (floating cylinder that produces smoke and flames for 40-60 minutes) approximately two miles downwind to assist in executing an instrument approach to a hover above the water’s surface. ⁶
Lewis had to make a crucial decision. Peering at the fog below him, he remembers asking himself a question to plunge or not to plunge. ⁷ Lewis knew that the answer could spell a chance at life for the seriously ill merchant seaman. However, there was also his crew, his co-pilot, a radio operator, a corpsman and the aviation survivalman who operated the rescue hoist. Their lives and his own also were at stake. “I decided to lower the helicopter down to the water,” he said in an interview. “By then it was pitch dark. I flew away from where our radar told us the ship was and then went down to about 40 feet from the ocean.” ⁸
Diagram Caption: overhead view of the HH-3F PATCH (Precision Approach to a Coupled Hover) a procedure very similar to the “beep-to-hover”.
To transition from forward flight to a hover, #1473 executed a challenging “beep-to-hover” maneuver, which enabled them to safely approach the water and the ship. The “beep-to-hover” maneuver was developed by LCDR Frank Shelley, test pilot and program manager for HH-52A acquisition testing, to help pilots safely transition to an overwater hover at night and/or in instrument conditions. The HH-3F PATCH (precision approach to a coupled hover) eventually replaced the “beep-to-hover” in late-1971. ⁹ Interestingly, both procedures most closely mimic the ‘early’ MATCH (manual approach to a controlled hover) in the H-60 and H-65 series aircraft – the PATCH and CATCH in these aircraft utilize auto-pilot and trim functions to perform a ‘hands off’ coupled approach to the water.
This “beep-to-hover” maneuver can be disorienting in the clouds at night, particularly when low over the water with little room for error. Both pilots must continuously scan and interpret the flight instruments – this is critically important – while smoothly manipulating the controls to ensure they are hitting various airspeed and altitude windows to fly the correct profile.
At the completion of this very demanding approach, the helicopter crew found itself in nearly “zero-zero” weather but had executed the approach with such precision that the MK-58s were located. ¹⁰ Barely establishing visual reference with the ocean surface from a 40-foot hover, the helicopter crew was unable to see the vessel’s lights and therefore was hovering at night in a dense fog with minimal visual reference with the ocean surface.
“We made what amounted to an instrument approach to the water,” Lewis explained, “Hovering just over the waves we crawled toward the ship which was about two to three miles away.” ¹¹ At least that’s where a little black box on the instrument panel said the ship was. The aircrew inched forward using the helicopter doppler hover system, the radar, the RDF (radio direction finding, which provided a bearing to a radio signal from the ship). At about one mile out, the STEEL EXECUTIVE’s blip on the helicopter radar was lost in surface clutter – the mood was tense with the aircrew concerned about the combination of low visibility, closure rate, low altitude and vessel rigging obstacles. ¹² At an altitude of 40 feet in extremely limited visibility, the helicopter could literally stumble into the vessel, causing a collision that would doom everyone on board the aircraft and imperil the ship’s crew as well. Eventually, the ship’s surface search radar picked up the helicopter and guided it to her. ¹³ Farmer was on a gunner’s belt leaning out the cabin door and straining to find the ship’s glow. ¹⁴
Lewis praised ASM2 Larry Farmer for far exceeding the scope of duties he’d been trained for – hoisting the injured man off his ship and onto the hovering aircraft. “Farmer actually guided me to the ship.” Lewis said, “I had no visual references so I depended entirely on him. He became our aircraft’s eyes and brought us over the freighter.” ¹⁵
Pucker factor is a slang phrase used by military aviators to describe the level of stress and/or adrenaline response to danger or a crisis situation. The term refers to the tightening of the sphincter caused by extreme concern – on particularly challenging missions, the seat cushions might go missing altogether. The pucker factor had been high since the initial descent into the fog bank, however Farmer remarked that “finally gaining a visual with the ship eased the pucker factor and transformed the aircrew’s outlook from uncertainty of success to ‘we can do this’.” ¹⁶
Huge spotlights pierced the fog, but all Lewis and Farmer could see was the hoist аrеа. Even under ideal weather conditions, positioning a hovering helicopter over the crowded decks of a freighter is a delicate maneuver. “Doing it in pitch darkness while howling 25-mile an hour winds rock ship and aircraft alike is – in the words of the young crewmen who were there with Lewis – something else”. ¹⁷
Diagram Caption: HH-3F #1473’s approximate hoisting position with STEEL EXECUTIVE (represented with a generic Type C3 cargo ship plan of roughly the same arrangement).
The pilot and flight mechanic were still concerned with the helicopter’s low hoisting altitude as they surveyed the vessel obstacles – the ship’s towering rigging literally disappeared in the fog above. ¹⁸ Much of the obstacle clearance judgement and decision making fell on the flight mechanic’s shoulders as the pilot was unable to see the hoisting area behind him. The crew was convinced that a ‘basket with trail line’ was the right technique for the situation as it would allow the helicopter to hoist from a position offset 30-40 feet from the ship and facilitate Lewis’ use of the STEEL EXECUTIVE as a hover reference. A trail line is a 105-foot piece of polypropylene line (similar to a water ski rope) with a 300-pound weak-link at one end and a weight bag at the other. The weight bag end of the trail line is paid out below the helicopter and delivered to the persons in distress (usually vertically, but seasoned flight mechanics can literally ‘cast’ the weight bag to a spot). The weak link is then attached to the hoist hook and the helicopter backs away until the pilot can see the hoisting area. The persons in distress can then pull the basket to their location – creating a hypotenuse or diagonal – as opposed to a purely vertical delivery.
Farmer carefully conned the helicopter over the vessel providing voice commands to the pilot – delivering the trail line and, subsequently, the rescue basket to the stern of the STEEL EXECUTIVE. The semi-ambulatory patient was assisted into the basket by the ship’s crew and then hoisted aboard the helicopter. Lewis and Farmer were able to complete the hoist on the first attempt. Farmer appreciatively described Desimone’s efforts: “he spent most of his time working the radios, but he assisted me during the hoists. He was the extra set of hands getting the rescue basket into the cabin and then clearly directed the patient to the back of the cabin.” ¹⁹ Petty Officer McCollough secured the patient for the flight, administered antibiotics and maintained constant watch on the patient’s condition during the return flight. ²⁰
Often forgotten was the job done by Fullmer as Safety Pilot. He continuously scanned the system instruments to ensure the aircraft was operating normally and monitored the flight instruments to ensure obstacle clearance and safe altitude. He effectively conveyed critical information without interfering with Farmer’s conning commands. ²¹
After completing the hoist, it took a few minutes to secure the cabin – Farmer stowed the basket and secured the hoist hydraulics, then closed the cabin door and reported the cabin was secured and ready for forward flight. The pilots then executed a demanding night instrument take-off or ITO from a hover over the water. The ITO is similar to the “beep-to-hover” in terms of relying on aircraft instruments instead of visual cues, but its purpose is the opposite – to get you away from the water and into a forward flight profile at a safe airspeed and altitude. The maneuver was flawlessly executed and the aircrew soon found themselves above the fog bank in clear skies. The helicopter returned to San Diego to deliver the patient to medical authorities. The STEEL EXECUTIVE crewman subsequently recovered. ²²
LCDR Lewis earned the Distinguished Flying Cross for this mission, while ASM3 Farmer earned the Air Medal. The medals were presented by RADM James Williams, Commander, 11th Coast Guard District, in a ceremony at Air Station San Diego on 23 February 1972.
The Lewis and Farmer citations are below:
LCDR Lewis also earned the American Helicopter Society (now the Vertical Flight Society) Frederick L. Feinberg Award on 19 May 1972 at the Sheraton-Park Hotel, Washington, D. C – presented to the pilot or crew of a vertical flight aircraft who demonstrated outstanding skills or achievement during the preceding 18 months.
The award was presented by RADM William A. Jenkins, Chief, Office of Operations, Coast Guard Headquarters, who outlined the case as follows:
“Commander Lewis was selected for his sea rescue of an ill crewman from the merchant ship, S.S. Steel Executive, at night and under extremely hazardous weather conditions. Despite very dense fog, Lt. Cdr. Lewis took off and proceeded to the estimated position of the vessel some 220 miles south of San Diego, Calif. , and — by applying extremely skillful instrument approach procedures — was able to find the vessel with visibility reduced to an eighth of a mile and less at times, and by hovering 50 feet above the vessel, he rescued its seriously ill crewman and safely delivered the patient to medical authorities. The crewman subsequently recovered. This demonstration of courage, skill and airmanship has deservingly earned him the Frederick L. Feinberg Award.” ²³
LCDR Lewis provided the following acceptance speech:
“It’s indeed a deep personal honor for me to receive this award from the American Helicopter Society and from the Kaman organization. But in a sense I really feel that it’s unfortunate that this award should be given to an individual. Without attempting to feign false modesty, I sincerely feel that this award should be shared with many others; specifically the other 3 members of my crew, my service — the Coast Guard — and really, in a sense, you, the members of the American helicopter industry. I am sure there are people sitting here in the audience this evening that participated in the design, the development, and the production of the very fine Sikorsky HH-3 helicopter that was used in this rescue. In honoring the Coast Guard by my selection, I really feel that you honored a service that from the helicopters very beginning — we employed it to rescue thousands of people and saved millions of dollars of property. My rescue that is honored here this evening is really very typical of many other rescues that the Coast Guard has accomplished. And so — even though it’s my name alone that is on this award — I sincerely believe that the honor belongs to my entire crew for that evening that this rescue was accomplished and I feel also that it should be shared with the many other Coast Guard crews who accomplished many other rescues of equal ability or what may it be, but I feel I should share the honor with them.” ²⁴
Later that summer (1972), LCDR Lewis transferred to Air Station St. Petersburg, FL where he continued flying the HH-3F helicopter. Unfortunately, six months after the Feinberg Award presentation, on 16 December 1972, HH-3F #1474 assigned to Air Station St. Petersburg was lost off Sarasota along with the crew LCDR Paul R. Lewis, MAJ Marvin A. Cleveland, USAF (Exchange pilot), AD1 Edward J. Nemetz, AT3 Clinton A. Edwards, and four rescued crewmen from the 54-foot fishing vessel WANDA DENE William Peek, George Dayhoss, Herbert Hardy and Paul Manley. It was late on Saturday when the WANDA DENE, sent out a distress call. The stricken vessel was 35 miles southwest of Key West, taking on water and sinking in rough seas. HH-3F #1474 was launched with its crew of four for a long range rescue. The helicopter arrived overhead the WANDA DENE several hours later and successfully hoisted the four crewmen from the sinking vessel in challenging conditions. The #1474 then flew to Naval Air Station Key West to refuel. From there #1474, now with eight people aboard, departed at about 7 PM for a return flight to St. Petersburg. Normal flight operations were reported with regular radio position reports until about 8:30 PM. Two days later a small portion of the helicopter was found in the Gulf of Mexico south of Fort Myers. Despite a massive search, very little of the aircraft and only one body, that of one of the fisherman, was ever recovered. The cause of the crash was never determined.
On 04 March 2011, a dedication ceremony was held at Air Station Clearwater, FL to posthumously name an annex building in honor of the Service and Sacrifice displayed by LCDR Paul R. Lewis. Members of the Lewis Family including daughter Kara Lewis, wife, Jackie Lewis, sister Abby Sauer, son Curt Lewis, daughter Megan Lewis, sister Joan Chaffee, and Abby’s husband, Gene Sauer were in attendance. Here is a section of the presentation that was made that day:
“LCDR Lewis was a tall, athletic Coast Guard Academy graduate who was regarded as the type of officer and pilot that others strive to become. He graduated in 1960, and went to serve his time aboard a Coast Guard cutter before attending flight school.
Prior to being stationed at Air Station St. Petersburg, LCDR Lewis served at the following air stations: Miami, Kodiak and San Diego. LCDR Lewis was known for his exceptional crew resource management and inclusion of his crew in all his flying duties. Among the pilots he was heralded as a flight instructor and examiner who knew the aircraft better than anyone.
LCDR Lewis is notably remembered for being the first Coast Guard pilot awarded the Frederick L. Feinberg Award for a rescue he performed offshore in San Diego. For that same rescue, he was awarded the Distinguished Flying Cross.”
While the building was named to honor Lewis, the air station believed Lewis would have wanted to honor the service and sacrifice of his crew as well. Hence, the auditorium within the building was named for Major Cleveland, the conference room for AD1 Nemetz, and the training room for AT3 Edwards.

Retired CAPT Sean M. Cross served 25 years in the Coast Guard as a helicopter pilot and aeronautical engineer. Flying both the MH-60T and MH-65D, he accumulated over 4,000 flight hours while assigned to Air Stations Clearwater, FL; Cape Cod, MA; San Diego, CA; Elizabeth City, NC and Traverse City, MI – which he commanded.
“LCDR Paul R. Lewis is first Coast Guard Aviator name etched on the Feinberg Award and the story of HOW it got there should be preserved for posterity.”
Convair B-36J-75-CF Peacemaker, 52-2827, the last B-36 built. (U.S. Air Force)
The Last Peacemaker: This gigantic airplane, a Convair B-36J-75-CF Peacemaker, serial number 52-2827, was the very last of the ten-engine strategic bombers built by the Convair Division of General Dynamics at Fort Worth, Texas. It was completed 1 July 1954. On 14 August, it was delivered to the Strategic Air Command, 92nd Bombardment Wing, Heavy, at Fairchild Air Force Base, Washington. In April 1957, 52-2827 was assigned to the 95th Bombardment Wing, Heavy, at Biggs Air Force Base, El Paso, Texas.
The last one built, 52-2827 was also the last operational B-36.

On 12 February 1959, after 4 years, 5 months, 30 days service, the Air Force returned the bomber to Fort Worth. 52-2827 departed Biggs Air Force Base at 11:00 a.m., under the command of Major Frederick J. Winter. Other pilots were Colonel Gerald M. Robinson, commanding the 95th Wing, and Captain Wilson P. Smith. (Colonel Robinson flew as first pilot during the takeoff, while Major Winter flew the landing.) The bomber’s crew were hand-picked, and included two navigators, two flight engineers, an observer, two radio operators, two gunners and a crew chief. Ten newspaper, radio and television reporters were on board as well.
Crew of City of Fort Worth
The B-36 touched down at Amon Carter Field at 2:55 p.m. The Peacemaker’s log book was closed out with a total of 1,414 hours, 50 minutes, flight time.
After a ceremony attended by thousands, the bomber was officially retired. A bugler blew “Taps,” and then the Peacemaker was towed away.
It was put on display at Amon Carter Field. After decades of neglect, the bomber was placed in the care of the Pima Air and Space Museum at Tucson for restoration and display.

Convair B-36J 52-2827 is one of 14 “Featherweight III” high altitude variants. It was built without the six retractable defensive gun turrets of the standard B-36, retaining only the two M24A1 20 mm autocannons in the tail. This reduced the crew requirement to 13. It is 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 9 inches (14.249 meters). The empty weight is 166,125 pounds (75,353 kilograms) and loaded weight is 262,500 pounds (119,068 kilograms). Maximum takeoff weight is 410,000 pounds (185,973 kilograms).
The B-36J has ten engines. There are six air-cooled, supercharged 4,362.49 cubic-inch-displacement (71.488 liter) Pratt & Whitney Wasp Major C6 (R-4360-53) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. The R-4360-53 had a Normal Power rating of 2,800 horsepower at 2,600 r.p.m. Its Military Power rating was 3,500 horsepower at 2,800 r.p.m., and 3,800 horsepower at 2,800 r.p.m. with water injection—the same for Takeoff. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-53 is 9 feet, 9.00 inches (2.972 meters) long, 4 feet, 7.00 inches (1.397 meters) in diameter, and weighs 4,040 pounds (1,832.5 kilograms).
Four General Electric J47-GE-19 turbojet engines are suspended under the wings in two-engine pods. The J47 is a single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilonewtons).
The B-36J Featherweight III had a cruise speed of 230 miles per hour (370 kilometers per hour) and a maximum speed of 418 miles per hour (673 kilometers per hour). The service ceiling was 43,600 feet (13,289 meters) and its combat radius was 3,985 miles (6,413 kilometers). The maximum range was 10,000 miles (16,093 kilometers).
The B-36 was designed during World War II and nuclear weapons were unknown to the Consolidated-Vultee Aircraft Corporation engineers. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in the four-section bomb bay. It could carry the 43,600 pound (19,777 kilogram) T-12 Cloudmaker, a conventional explosive earth-penetrating bomb. When armed with nuclear weapons, the B-36 could carry several Mk.15 3.8 megaton thermonuclear bombs. By combining the bomb bays, one Mk.17 15-megaton thermonuclear bomb could be carried.

TDiA has received an number of comments recently regarding the safety of the Convair B-36 Peacemaker strategic bomber. Based on our research, out of the 384 built, 27 B-36s were lost in accidents between 1950 and 1957, amounting to just 7% of the fleet. 165 crew members were killed. The most common cause seems to be a fire following a landing gear collapse. The first, a B-36B, was lost on 14 February 1950. That incident is described at https://www.thisdayinaviation.com/13-february-1950/ . On 27 April 1951, a flight of four North Americaan Aviation F-51D Mustangs attacked a B-36D over Oklahoma. One fighter collided with the bomber, which crashed, resulting in the death of 12 of the 17 airmen on board. (The F-51D pilot was also killed.) 6 May 1951, a B-36D crashed while attempting to land in high winds at Kirtland AFB, New Mexico. 23 of 25 on board were killed. 22 August 1951, a taxiing RB-36E collided with a parked RB-36E, which was destroyed. No injuries. 29 January 1952, a B-36D landed short of the runway and skidded into a snow bank at Fairchild AFB, Washington. The aircraft was destroyed by fire, but there were no fatalities. 6 March 1952, a B-36F was destroyed by fire while parked. A fuel leak was caused when the left landing gear failed on landing. There were no fatalities. 15 April 1952, a B-36D overran the runway during a maximum weight takeoff at Fairchild AFB, WA, because flight control trim had been incorrectly set. The aircraft was destroyed by fire. 15 of 17 on board were killed. 28 May 1952, a B-36F returning to Carswell AFB after takeoff due to a loose cowling, crashed and caught fire when its landing gear collapsed on landing, 7 on board were killed. 4 August 1952. A B-36F was destroyed by fire while parked at Carswell AFB. While being fueled, gasoline overflowed from a fuel vent and was ignited by a ground power unit. No injuries or deaths. 13 February 1953, a B-36H was misdirected during a GCA approach to Goose Bay, Labrador. It crash landed on a hill. 2 of 17 on board were killed. 5 August 1952, a modified B-36D being flown by a Convair crew crashed in the ocean west of San Diego, California, when it’s number 5 engine caught fire, which then spread to the rest of the wing. 7 of 8 crewmen bailed out while the pilot remained at the controls to guide the bomber away from the populated area. He was killed. 1 crewman drowned. 4 crewmen received minor injuries. 18 February 1953, an RB-36H was destroyed by fire when it’s landing gear collapsed during landing at Walker AFB, New Mexico. Of the 22 on board there were no fatalities. 18 March 1953, an RB-36H was destroyed when it hit a hill in Labrador. The aircraft was off course and one-and-a-half hours ahead of schedule. All 23 on board were killed. 5 August 1953, an RB-36H went down in the Atlantic Ocean (cause not discovered at this time.) 19 of 23 on board were killed. 11 December 1953, a B-36D crashed into a mountain in poor visibility while on approach to Biggs AFB, Texas. (Not in GCA radar contact). 9 of 9 on board were killed. 26 February 1954, at Fairchild AFB, the landing gear of a taxiing B-36D collapsed, resulting in the aircraft being destroyed by fire. No fatalities among the 20 on board. 29 March 1954, a B-36D crashed while practicing a takeoff abort at Fairchild AFB. All 7 on board were killed. 27 August 1954, an RB-36H making its sixth practice night approach at Ellsworth AFB hit an obstruction on a hill with its left wing and crashed. (Obstruction lights were inoperative due to a lightning strike.) 26 of 27 on board were killed. [Altimeter was in error, GCA was out of calibration, resulting in the aircraft being 150 feet lower on the glide slope than it should have been.] 8 February 1955, a B-36D landed short of the runway during a practice landing at Carswell AFB, Texas. Landing gear was sheared off and the aircraft damaged beyond economical repair. No fatalities. 6 March 1955, a B-36D landing at Loring AFB, Maine, hit a wingtip on a snowbank, resulting in the aircraft being destroyed by fire. No fatalities but some (unknown how many) serious injuries among the 11 on board. 25 May 1955, a B-36J disintegrated in flight during a thunderstorm/tornado near Sterling City, Texas. All 15 on board were killed. (Lost outboard wing panels and all tail surfaces. Impacted in level attitude with little forward motion.) 4 January 1956, an RB-36H crashed on landing at Ellsworth AFB, South Dakota after uneven power reduction. Destroyed by fire. No fatalities. 19 January 1956, a B-36D made a hard landing at Biggs AFB, Texas. No fatalities. Aircraft damaged beyond economical repair. 15 November 1956, a B-36H lost power on takeoff from Lowry AFB, Colorado, due to fuel starvation. It crashed one mile short of the runway attempting an emergency landing at Stapleton Airport, Denver. Aircraft destroyed by fire. No fatalities among 21 on board. 6 June 1957, a B-36H was damaged beyond economical repair while flying through a thunderstorm near Carswell AFB, Texas. No fatalities. 9 November 1957, an RB-36H was destroyed by fire while parked at Ramey AFB, Puerto Rico. No fatalities… A major incident occurred 1 September 1952, when a tornado struck Carswell AFB. 61 B-36s on the ground were damaged. Most were repaired and returned to service within two weeks.
Sikorsky S-52 NC92823, serial number 52001. (Vertical Flight Society)
12 February 1947: The Sikorsky Model S-52, NC92823, made its first flight.
The S-52 was an completely new design helicopter based on the company’s experience with the earlier R-4 and R-5/S-51 models. It was a two-place light helicopter of monocoque construction, using primarily aluminum and magnesium.
This was the first Sikorsky helicopter to use an offset flapping hinge in the main rotor, which greatly increased the helicopter’s maneuverability. This feature has been incorporated in every Sikorsky helicopter from that time on.
The three-bladed fully-articulated articulated main and two-bladed tail rotor were also of all metal construction. The main rotor had a diameter of 33 feet (10.058 meters) and rotated counter-clockwise as seen from above. (The advancing blade is on the right side of the helicopter.) The blades were construced of aextruded aluminum spar with a sheet duralumin skin riveted and glued. The blades used the NACA 0012 airfoil, a symmetrical profile which was common in early helicopters. The blades had -6° twist.
The semi-rigid tail rotor was mounted on the left side of the tail boom in a pusher configuration. It had a diameter of 6 feet, 4 inches (1.930 meters) and rotated counter clockwise, as seen from the helicopter’s left. (The advancing blade is at the top of the tail rotor arc.)
The prototype was powered by an air-cooled, normally-aspirated, 333.991-cubic-inch-displacement (5.473 liter) Franklin Engine Company 6V4-165-B32F vertically-opposed 6-cylinder overhead valve engine, rated at 165 horsepower at 2,800 r.p.m. The S-52-1 that followed was equipped with a 425.29-cubic-inch-displacement (6.97 liter) Franklin 6V6-245-B16F (O-425-1). This engine was rated at 245 horsepower at 3,275 r.p.m.
The helicopter’s Civil Aeronautics Administration type certificate was approved 25 February 1948.
