A Pan American Airways Sikorsky S-42.

11 January 1938: Pan American Airways’ Sikorsky S-42B NC16734, Samoan Clipper, took off from Pago Pago, American Samoa, enroute Auckland, New Zealand. The airplane had a crew of seven, commanded by Captain Edwin C. Musick, the airline’s senior pilot, and a cargo of mail.

About two hours out, the number four engine began leaking oil. Captain Musick ordered the engine shut down. The flight radioed that they were returning to Pago Pago. They never arrived. Wreckage, a large oil slick, various documents and articles of the crew’s clothing were found by the U.S. Navy seaplane tender USS Avocet (AVP-4), 14 miles (22.5 kilometers) west of the island. It was apparent that the S-42 had exploded in mid-air.

The cause of the explosion is not known with certainty but based on Captain Musick’s handling of a similar problem with one of  Samoan Clipper‘s  engines on an earlier flight, a possible cause can be suggested.

On the earlier flight, the number four engine had begun seriously overheating and Musick ordered the flight engineer to shut it down. Because of the decreased power with only three engines, Captain Musick ordered the crew to begin dumping fuel to decrease the weight of the airplane before landing.

Pan American had tested the fuel dumping characteristics of the Sikorsky S-42 using dye, and had learned that because of the air flow patterns around the wings, the fluid tended to accumulate around the trailing edge of the wings and that it could actually be sucked into the wings themselves.

As fuel was being dumped on the previous flight, fuel vapors were present in the cabin, requiring all electrical systems to be shut off—even though it was night. Liquid gasoline was also dripping into the cockpit from the wing above.

Samoan Clipper had been very heavy with fuel when it departed for the long transoceanic flight to Auckland. Presuming that Captain Musick once again ordered fuel to be dumped prior to landing back at Pago Pago, and that the vapors collected around the wings, the fuel could have been detonated by the electrical motors which were used to lower the flaps for flight at slower speed, or by coming into contact with the hot exhaust of the engines.

Two independent investigations were carried out by Pan American and by the United States Navy, and both came to this conclusion.

There were no survivors of the explosion. Killed along with Captain Musick were Captain Cecil G. Sellers, Second Officer P.S. Brunk, Navigator F.J. MacLean, Flight Engineer J.W. Stickrod, Flight Mechanic J.A. Brooks and Radio Operator T.D. Findley.

The Sikorsky S-42B was a four-engine long-range flying boat built for Pan American Airways by the Vought-Sikorsky Aircraft Division of United Technologies at Stratford, Connecticut. It was 68 feet (20.726 meters) long with a wingspan of 118 feet, 2 inches (36.017 meters). The S-42 had an empty weight of 19,764 pounds ( kilograms) and gross weight of 38,000 pounds ( kilograms). It could carry up to 37 passengers.

The S-42B was powered by four air-cooled, supercharged, 1,690.537-cubic-inch-displacement (27.703 liters) Pratt & Whitney Hornet S1E-G nine-cylinder radial engines with a compression ratio of 6.5:1. The S1E-G had a Normal Power rating of 750 horsepower at 2,250 r.p.m., to 7,000 feet (2,134 meters), and 875 horsepower at 2,300 r.p.m., for Takeoff. The engines drove three-bladed Hamilton Standard constant-speed propellers through a 3:2 gear reduction. The S1E-G was 4 feet, 1.38 inches (1.254 meters) long, 4 feet, 6.44 inches (1.383 meters) in diameter, and weighed 1,064 pounds (483 kilograms).

The S-42B has a cruise speed 165 miles per hour (266 kilometers per hour) and maximum speed of 188 miles per hour (303 kilometers per hour) at 5,000 feet (1,524 meters). The service ceiling was 16,000 feet (4,877 meters), and it could maintain 7,500 feet (2,286 meters) with three engines. Its range was 1,930 miles (3,106 kilometers).

During flight testing of the S-42, Sikorsky test pilot Boris Vasilievich Sergievsky, with co-pilot Raymond B. Quick, set three Fédération Aéronautique Internationale world records for payload and altitude.¹  Later, Captain Musick, with Sergievsky and world-famous aviator Charles A. Lindbergh, flew the S-42 to set eight Fédération Aéronautique Internationale world records for speed.²

Ten Sikorsky S-42, S-42A and S-42B flying boats were built for Pan Am. None remain in existence.

11 January 1935: At 4:40 p.m., local time, Amelia Earhart departed Wheeler Field on the island of Oahu, Territory of Hawaii, for Oakland Municipal Airport at Oakland, California, in her Lockheed Vega 5C Special, NR965Y. She arrived 18 hours, 15 minutes later. Earhart was the first person to fly solo from Hawaii to the Mainland.

(This Vega was not the same aircraft which she used to fly the Atlantic, Vega 5B NR7952, and which is on display at the Smithsonian Institution National Air and Space Museum.)

Built by the Lockheed Aircraft Company, the Model 5 Vega is a single-engine high-wing monoplane designed by John Knudsen (“Jack”) Northrop and Gerrard Vultee. It was a very state-of-the-art aircraft for its time. It used a streamlined monocoque fuselage made of spiral strips of vertical grain spruce pressed into concrete molds and held together with glue. The wing and tail surfaces were fully cantilevered, requiring no bracing wires or struts to support them.

The techniques used to build the Vega were very influential in aircraft design. It also began Lockheed’s tradition of naming its airplanes after stars or other astronomical objects.

Lockheed Model 5C Vega serial number 171 was completed in March 1931, painted red with silver trim, and registered NX965Y. The airplane had been ordered by John Henry Mears. Mears did not take delivery of the new airplane and it was then sold to Elinor Smith. It was resold twice before being purchased by Amelia Earhart in December 1934.

The Lockheed Model 5C Vega is 27 feet, 6 inches (8.382 meters) long with a wingspan of 41 feet (12.497 meters) and overall height of 8 feet, 2 inches (2.489 meters). Its empty weight is 2,595 pounds (1,177 kilograms) and gross weight is 4,500 pounds (2,041 kilograms).

Earhart’s Vega 5C was powered by an air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp C, serial number 2849, a single-row, nine cylinder, direct-drive radial engine with a compression ratio of 5.25:1. The Wasp C was rated at 420 horsepower at 2,000 r.p.m. at Sea Level, burning 58-octane gasoline. It was 3 feet, 6.63 inches (1.083 meters) long with a diameter of 4 feet, 3.44 inches (1.307 meters) and weighed 745 pounds (338 kilograms).

The standard Model 5C had a cruise speed of 165 miles per hour (266 kilometers per hour) and maximum speed of 185 miles per hour (298 kilometers per hour). The service ceiling was 15,000 feet (4,570 meters) and range in standard configuration was 725 miles (1,167 kilometers).

“Before parting with her ‘little red bus’ (as she affectionately called it), Amelia removed the upgraded Wasp engine and substituted an obsolete model; she wanted her well-tried engine for the new airplane, also a Lockheed Vega. It was a later model, in which Elinor Smith had been preparing to be the first woman to fly the Atlantic, a plan abandoned after Amelia successfully took that record. It was originally built to exacting specifications for Henry Mears of New York, who had a round-the-world flight in mind. Called the Vega, Hi-speed Special, it carried the registration 965Y and was equipped with special fuel tanks, radio, and streamlined landing gear and cowling. These latter appointments, together with a Hamilton Standard Controllable-Pitch Propeller, gave the plane a speed of 200 mph and Amelia had her eye on further records as well as her constant journeys across the continent.”

“. . . At Oakland Airport a good ten thousand had been waiting for several hours, yet when she came in she surprised them. They had been craning their necks looking for a lone aircraft flying high and obviously seeking a place to land. But Amelia did not even circle the field; she brought the Vega in straight as an arrow at a scant two hundred feet, landing at 1:31 p.m. Pacific time. The crowd set up a roar, broke through the police lines, and could be halted only when dangerously near the still-whirling propeller. From the road circling the airport, a chorus of automobile horns honked happily.”

Amelia Earhart sold the Vega in 1936. It appeared in “Wings in the Dark,” (Paramount Pictures, 1935), and  “Border Flight,” (Paramount Pictures, 1936) which starred Frances Farmer, John Howard and Robert Cummings. It changed hands twice more before being destroyed in a hangar fire 26 August 1943.

10 January 1966: The prototype Bell Model 206A JetRanger serial number 1, N8560F, made its first flight at at the Bell Helicopter Company plant at Hurst, Texas. This aircraft would be in production for almost 45 years. The final JetRanger to be built, Bell 206B-3 serial number 4690, was delivered in December 2010 and production came to an end.

During early production of the Model 206A, cabin sections were built by Beechcraft and Agusta then shipped to Bell at Fort Worth. (The vertical seam just to the rear of the fuel cap distinguished the two.) Oil pressure and temperature gauges for the engine and transmission, the loadmeter and fuel quantity indicator were provided by Cessna.

The  Bell JetRanger is a 5-place, single-engine light civil helicopter based on the Bell Helicopter’s unsuccessful OH-4 entrant for the U.S. Army’s Light Observation Helicopter (LOH, or “loach”) contract. It is flown by a single pilot in the right front seat. Dual flight controls can be installed for a second pilot. The helicopter was certified for VFR flight, but could be modified for instrument flight.

The industrial design firm of Charles Wilfred Butler

“. . . was responsible for the complete redesign of the Bell OH-4A prototype army helicopter (1961) into the Bell Jet Ranger (1965). He and his designers restyled the machine inside and out in the manner of automotive design, creating in the process one of the world’s most successful and beautiful helicopters.”

—Encyclopedia Britannica.

The JetRanger is 38 feet, 9.5 inches (11.824 meters) long, overall. On standard skid landing gear the overall height is 9 feet, 4 inches (2.845 meters). The Bell 206A has an empty weight of approximately 1,700 pounds (771 kilograms), depending on installed equipment. The maximum gross weight is 3,200 pounds (1,451.5 kilograms). With an external load suspended from the cargo hook, the maximum gross weight is increased to 3,350 pounds (1,519.5 kilograms).

The two-bladed main rotor is semi-rigid and under-slung, a common feature of Bell’s main rotor design. It has a diameter of 33 feet, 4.0 inches (10.160 meters) and turns counter-clockwise (seen from above) at 394 r.p.m. (100% NR). (The advancing blade is on the helicopter’s right side.) The rotor blade has a chord of 1 foot, 1.0 inches (0.330 meter) and 10° negative twist. The airfoil is symmetrical. The cyclic and collective pitch controls are hydraulically-boosted.

The two-bladed tail rotor assembly is also semi-rigid and is positioned on the left side of the tail boom in a pusher configuration. It turns at 2,550 r.p.m., clockwise, as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.) The tail rotor diameter is 5 feet, 6.0 inches (1.676 meters).

The turboshaft engine is mounted above the roof of the fuselage, to the rear of the main transmission. Output shafts lead forward to the transmission and aft to the tail rotor 90° gear box. The transmission and rotor mast are mounted tilting slightly forward and to the left. This assists in the helicopter’s lift off to a hover, helps to offset its translating tendency, and keeps the passenger cabin in a near-level attitude during cruise flight.

A vertical fin is attached at the aft end of the tail boom. The fin is offset 4° to the right to unload the tail rotor in cruise flight. Fixed horizontal stabilizers with an inverted asymmetric airfoil are attached to the tail boom. In cruise flight, these provide a downward force that keeps the passenger cabin in a near-level attitude.

The 206A was powered by an Allison 250-C18 turboshaft engine (T63-A-700) which produced a maximum of 317 shaft horsepower at 104% N1, 53,164 r.pm. The improved Model 206B JetRanger and 206B-2 JetRanger II used a 370 horsepower 250–C20 engine, and the Model 206B-3 JetRanger III had 250-C20B, -C20J or -C20R engines installed, rated at 420 shaft horsepower at 105% N1, (53,519 r.p.m.). Many 206As were upgraded to 206Bs and they are sometimes referred to as a “206A/B.” The Allison 250-C20B has a 7-stage compressor section with 6-stage axial-flow stages, and 1 centrifugal-flow stage. The 4-stage axial-flow turbine has a 2-stage gas producer (N1) and 2-stage power turbine (N2). These were very light weight engines, ranging from just 141 to 173 pounds (64.0 to 78.5 kilograms).

The helicopter’s main transmission is limited to a maximum input of 317 shaft horsepower (100% Torque, 5-minute limit). The engine’s accessory gear unit reduces the output shaft speed to 6,016 r.p.m. N2, which is further reduced by the transmission’s planetary gears, and the tail rotor 90° gear box.

The JetRanger has a maximum speed, VNE, of 150 miles per hour (241 kilometers per hour) up to 3,000 feet (914 meters). Its best rate of climb, VY, is at 60 miles per hour (97 kilometers per hour) and best speed in autorotation (minimum rate of descent and maximum distance) is at 80 miles per hour (129 kilometers per hour), resulting in a glide ratio of about 4:1. The service ceiling is 13,500 feet (4,145 meters) with the helicopter’s gross weight above 3,000 pounds (1,361 kilograms), and 20,000 feet (6,096 meters) when below 3,000 pounds. The helicopter has a maximum range of 430 miles (692 kilometers).

After being used as a factory demonstrator and development aircraft, N8560F was retired from flight status and used as a maintenance ground training device at Bell’s training school at Hurst.

Note: The Model 206A-1 was adopted by the U.S. Army as the OH-58A Kiowa. Though very similar in appearance to the Model 206A and 206B, the OH-58A differs significantly. Few of the parts are interchangeable between the types.

10 January 1964: This Boeing B-52H Stratofortress, serial number 61-023, flown by Boeing test pilot Charles F. (“Chuck”) Fisher, was conducting structural testing in turbulence near East Spanish Peak, Colorado. The other crew members were pilots Richard V. Curry and Leo Coer, and navigator James Pittman. Dick Curry was flying the airplane and Chuck Fisher, the aircraft commander, was in the co-pilot’s position. Pittman was on the lower deck.

The bomber was carrying two North American Aviation GAM-77 Hound Dog cruise missiles on pylons under its wings.

The Boeing B-52 Stratofortress had been designed as a very high altitude penetration bomber, but changes in Soviet defensive systems led the Strategic Air Command to change to very low altitude flight as a means of evading radar. This was subjecting the airframes to unexpected stresses. “Ten-Twenty-Three” (its serial number was 61-023, shortened on the vertical fin to “1023”) had been returned to Boeing Wichita by the Air Force to be instrumented to investigate the effects of high-speed, low-altitude flight on the 245-ton bomber.

Flying at 14,300 feet (4,359 meters) and 345 knots (397 miles per hour, 639 kilometers per hour), indicated air speed, the airplane encountered severe clear air turbulence and lost the vertical stabilizer. Several B-52s had been lost under similar circumstances. (Another, a B-52D, was lost just three days later at Savage Mountain, Maryland.)

Chuck Fisher immediately took control of the B-52. He later reported,

“As the encounter progressed, a very sharp-edged blow which was followed by many more. We developed an almost instantaneous rate of roll at fairly high rate. The roll was to the far left and the nose was swinging up and to the right at a rapid rate. During the second portion of the encounter, the airplane motions actually seemed to be negating my control inputs. I had the rudder to the firewall, the column in my lap, and full wheel, and I wasn’t having any luck righting the airplane. In the short period after the turbulence I gave the order to prepare to abandon the airplane because I didn’t think we were going to keep it together.”

A Boeing report on the incident, based on installed sensors and instrumentation aboard -023, said that the bomber had

“. . . flown through an area containing the combined effects of a (wind) rotor associated with a mountain wave and lateral shear due to airflow around a mountain peak. . . Gust initially built up from the right to a maximum of about 45 feet per second [13.7 meters per second](TAS), then reversed to a maximum of 36 feet per second [11 meters per second] from the left, before swinging to a maximum of about 147 feet per second [44.8 meters per second] from the left followed by a return to 31 feet per second [9.5 meters per second].”

Fisher flew the bomber back to Wichita and was met by a F-100 Super Sabre chase plane. When the extent of the damage was seen, the B-52 was diverted due to the gusty winds in Kansas. Six hours after the damage occurred, Chuck Fisher safely landed the airplane at Eaker Air Force Base, Blythville, Arkansas. He said it was, “the finest airplane I’ve ever flown.”

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It has a crew of five. The airplane is 159 feet, 4 inches (48.6 meters) long, with a wing span of 185 feet (56.4 meters). It is 40 feet, 8 inches (12.4 meters) high to the top of the vertical fin. Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

There are eight Pratt & Whitney TF33-PW-3 turbofan engines mounted in two-engine pods suspended under the wings on four pylons. Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, 14-stage compressor stages (7 stage intermediate pressure, 7 stage high-pressure) and and 4-stage turbine (1 stage high-pressure, 3-stage low-pressure). The engine is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (15,377 kilograms).

The B-52H can carry approximately 70,000 pounds (31,750 kilograms) of ordnance, including free-fall bombs, precision-guided bombs, thermonuclear bombs and cruise missiles, naval mines and anti-ship missiles.

The bomber’s cruise speed is 520 miles per hour (837 kilometers per hour) and its maximum speed is 650 miles per hour (1,046 kilometers per hour) at 23,800 feet (7,254 meters) at a combat weight of 306,350 pounds. Its service ceiling is 47,700 feet (14,539 meters) at the same combat weight. The unrefueled range is 8,000 miles (12,875 kilometers).

With inflight refueling, the Stratofortress’s range is limited only by the endurance of its five-man crew.

The B-52H is the only version still in service. 102 were built and as of June 2019, 76 are still in service. Beginning in 2013, the Air Force began a fleet-wide technological upgrade for the B-52H, including a digital avionics and communications system, as well as an internal weapons bay upgrade. The bomber is expected to remain in service until 2040.

10 January 1956: First Lieutenant Barty Ray Brooks, United States Air Force Reserve, a pilot assigned to the 1708th Ferrying Wing, Detachment 12, at Kelly Air Force Base, Texas, along with two other pilots from the same unit, Captain Rusty Wilson and Lieutenant Crawford Shockley, picked up three brand new F-100C Super Sabre fighters at the North American Aviation Inc. assembly plant at Air Force Plant 42, Palmdale, California. It was to be a short flight, as these three jets were being taken to nearby George Air Force Base, Adelanto, California, only 42.5 miles (68.4 kilometers) to the east. Brooks was flying F-100C-20-NA, serial number 54-1907.

The brief flight was uneventful until the pilots lowered the landing gear to land at George AFB. One of the other pilots saw that the scissors link joining the upper and lower sections of the nose gear strut on Brooks’ Super Sabre was loose. Concerned that he would not be able to steer the fighter after touching down, Brooks diverted to Edward Air Force Base, 36 miles (57 kilometers) to the northwest, where a larger runway and more emergency equipment was available. Captain Wilson escorted Lieutenant Brooks to Edwards.

The F-100C Super Sabre had no flaps and required a high speed landing approach. Lieutenant Brooks had only 674 total flight hours as a pilot, and just 39 hours in the F-100.

During his final approach to the runway Brooks allowed the fighter to slow too much and the outer portion of the wings stalled and lost lift. This shifted the wings’ center of lift forward, which caused the airplane to pitch up, causing even more of the outer wing to stall.

Lieutenant Brooks fought to regain control of the airplane, but he was unable to. At 4:27 p.m., Pacific Standard Time, the F-100 crashed on the runway and exploded. Barty Ray Brooks was killed.

Edwards Air Force Base is the center of flight testing for the U.S. Air Force. In preparation for a test later that afternoon, the base film crews had their equipment set up along the runway and captured the last seconds of Brook’s flight on film. This is the most widely seen crash footage, and is still in use in pilot training. It is named “The Sabre Dance.”

While at Texas A&M, Brooks was a member of the Reserve Officers Training Corps (R.O.T.C.). On graduation, 30 May 1952, Brooks was commissioned as a second lieutenant, United States Air Force Reserve.

Lieutenant Brooks was trained as a pilot at Columbus Air Force Base, Mississippi, and Laredo Air Force Base, Texas. In 1954, he was assigned to the 311th Fighter Bomber Squadron, 58th Fighter Bomber Group, Taegu Air Base (K-2), Republic of South Korea. Brooks flew the Republic F-84 Thunderjet and North American Aviation F-86 Sabre. When he returned to the United States he was assigned to the 1708th Ferrying Wing.

The remains of 1st Lieutenant Barty Ray Brooks were interred at the Round Grove Cemetery, Lewisville, Texas.
