15 April 1952: At 11:08 a.m., Boeing’s Chief of Flight Test, Alvin M. “Tex” Johnston, and Lieutenant Colonel Guy M. Townsend, U.S. Air Force, ran all eight turbojet engines to full power and released the brakes on the YB-52 Stratofortress prototype, 49-231.

With an awesome eight-engine roar, the YB-52 sprang forward, accelerating rapidly, wings curving upward as they accepted the 235,000-pound initial flight gross weight. At V2 (takeoff speed) the airplane lifted off the runway, because of the 6-degree angle of incidence of the wing, and at 11:08 a.m. we were airborne. The initial flight of the YB-52 had begun.

The YB-52 remained over the Seattle area for approximately 40 minutes while Johnson and Townsend ran through a series of systems checks. When completed, they climbed to 25,000 feet (7,620 meters) and flew the new bomber to Larson Air Force Base at Moses Lake, Washington, where they stayed airborne for continued testing. The Stratofortress finally touched down after 3 hours, 8 minutes—the longest first flight in Boeing’s history up to that time. Johnston radioed that the airplane performed exactly as the engineers had predicted.

The YB-52 had actually been ordered as the second of two XB-52s, but modifications and additional equipment installed during building resulted in enough differences to warrant a designation change. The first XB-52, 49-230, should have been the first to fly, but it was damaged during ground testing.

The Boeing XB-52 and YB-52 were prototypes for a very long range strategic bomber. Both were built with a tandem cockpit for the pilot and co-pilot, similar to the earlier B-47 Stratojet. The wings were swept and mounted high on the fuselage (“shoulder-mounted”). The eight turbojet engines were in in two-engine nacelles mounted on pylons, below and forward of the wings. This had the effect of preventing the airplane’s center of gravity from being too far aft, and also provided cleaner air flow across the wings. The B-52’s landing gear has four main struts with two wheels, each. They can turn to allow the airplane to face directly into the wind while the landing gear remain aligned with the runway for takeoff and landing. With the landing gear under the fuselage, the wings could be constructed with greater flexibility.

The YB-52 was 152 feet, 8 inches (46.533 meters) long with a wingspan of 185 feet, 0 inches (56.388 meters). The prototype’s overall height was 48 feet, 3.6 inches (14.722 meters). The vertical fin could be folded over to the right so that the B-52 could fit into a hangar. The total wing area was 4,000 square feet (371.6 square meters). The wings’ leading edges were swept aft to 36° 54′. Their angle of incidence was 6° and there was 2° 30′ dihedral. The YB-52 had an empty weight of 155,200 pounds (70,398 kilograms) and gross weight of 405,000 pounds (183,705 kilograms).

The YB-52 was powered by eight Pratt & Whitney Turbo Wasp YJ57-P-3 turbojet engines. The J57 was a two-spool, axial-flow turbojet developed from an experimental turboprop engine. It had 16-stage compressor section (9 low- and 7-high-pressure stages), 8 combustors and a 3-stage turbine section (1 high- and 2 low-pressure stages). The YJ57-P-3s had a continuous power rating of 8,700 pounds of thrust (38.70 kilonewtons). The YJ57-P-3 was 183.5 inches (4.661 meters) long, 41.0 inches (1.041 meters) in diameter and weighed 4,390 pounds (1,991 kilograms).

The YB-52 had a cruise speed of 519 miles per hour (835 kilometers per hour) and maximum speed of 611 miles per hour (983 kilometers per hour) at 20,000 feet (6,096 meters). Its range was 7,015 miles (11,290 kilometers).

The two prototypes were unarmed.

The B-52 was produced by Boeing at its plants in Seattle and Wichita from 1952 to 1962, with a total of 744 Stratofortresses built. The last version, the B-52H, entered service with the Strategic Air Command in 1960. The final B-52, B-52H-175-BW Stratofortress 61-0040, was rolled out at Wichita, Kansas, 26 October 1962. This airplane remains in service with the United States Air Force. The newest B-52 in service, 61-0040 is 62 years old and has flown more than 21,000 hours.

All previous versions, B-52A through B-52G, have long been retired to The Boneyard and scrapped. Of the 102 Boeing B-52H Stratofortress bombers, 76 are still in the active inventory. One, 61-007, known as Ghost Rider, was recently taken from Davis-Monthan and after an extensive restoration and update, returned to service.

The YB-52 prototype was retired to the National Museum of the United States Air Force in the late 1950s. By the mid-60s it was determined to be excess and was scrapped.

In one of the most dramatic photographic images of World War II, “Wee Willie,” Boeing B-17G-15-BO Flying Fortress 42-31333, is going down after it was hit by antiaircraft artillery over Stendal, Saxony-Anhalt, Germany, 8 April 1945. (American Air Museum in Britain, Roger Freeman Collection.)

8 April 1945: Wee Willie, a Flying Fortress heavy bomber, left its base at Air Force Station 121 (RAF Bassingbourne, Cambridgeshire, England), on its 129th combat mission over western Europe. The aircraft commander was 1st Lieutenant Robert E. Fuller, U.S. Army Air Forces.

Wee Willie was a B-17G-15-BO, serial number 42-31333, built by the Boeing Airplane Company’s Plant 2, Seattle, Washington. It was delivered to the United States Army Air Forces at Cheyenne, Wyoming on 22 October 1943, and arrived at Bassingbourne 20 December 1943. It was assigned to the 322nd Bombardment Squadron (Heavy), 91st Bombardment Group (Heavy), 1st Air Division, 8th Air Force. The identification letters LG W were painted on both sides of its fuselage, and a white triangle with a black letter A on the top of its right wing and both sides of its vertical fin.

On 8 April 1945, the 322nd Bombardment Squadron was part of an attack against the locomotive repair facilities at the railroad marshaling yards in Stendal, Saxony-Anhalt Germany. The squadron was bombing through clouds using H2S ground search radar to identify the target area. Antiaircraft gunfire (flak) was moderate, causing major damage to four B-17s and minor damage to thirteen others. Two bombers from the 91st Bomb Group were lost, including Wee Willie.

The Missing Air Crew Report, MACR 13881, included a statement  from a witness:

We were flying over the target at 20,500 feet [6,248 meters] altitude when I observed aircraft B-17G, 42-31333 to receive a direct flak hit approximately between the bomb bay and engine. The aircraft immediately started into a vertical dive. The fuselage was on fire and when it had dropped approximately 5,000 feet [1,524 meters] the left wing fell off. It continued down and when the fuselage was about 3,000 feet [914.4 meters] from the ground it exploded and then exploded again when it hit the ground. I saw no crew member leave the aircraft or parachutes open.

This photographic image precedes the one above. The Boeing B-17G-15-BO Flying Fortress 42-31333, Wee Willie, is engulfed in flame. The left wing has separated and is crossing over the fuselage. (American Air Museum in Britain)

The pilot, Lieutenant Fuller, did escape from the doomed bomber. He was captured and spent the remainder of the war as a Prisoner of War. The other eight crew members, however were killed.

During the 129 missions “Wee Willie” flew in its 1 year, 3 months, 20 days at war, many airmen served as its crew members. The men in this photograph are not identified, and the date it was taken is not known. A battle-scarred veteran, “Wee Willie” now has markings showing 106 missions completed. These men are representative all the aircrews who fought and died in the skies over Europe. The officer kneeling in the front row, right, has been identified as 2nd Lieutenant Jess Ziccarello, the navigator for this crew. Lieutenant Colonel Ziccarello passed away 2 October 2019 at the age of 96 years. Thanks to his son, Rick Ziccarello, for the identification. (American Air Museum in Britain)

Lieutenant Robert K. Giavannoli

8 March 1936: First Lieutenant Robert Kinnaird Giovannoli, United States Army Air Corps, a test pilot assigned to the Material Division at Wright Field, Ohio, was killed when the right wing of his Boeing P-26 pursuit, serial number 32-414, came off in flight over Logan Field, near Baltimore, Maryland.

The Cincinnati Enquirer reported:

DAYTON HERO

Air Crash Victim.

Robert Giovannoli Dies At Baltimore Field

When Wing Of Plane Falls Off—Lexington, Ky., Man An Army Lieutenant.

     Baltimore, March 8—(AP)—Lieutenant Robert K. Giovannoli, 31 years old of Lexington, Ky., hero of the spectacular bombing plane crash during army tests at Dayton, Ohio, last October, was killed today in the crack-up of his army plane at Logan Field, here.

     Giovannoli’s single-seated pursuit plane lost its right wing coming out of a glide and hurtled down in a crazy spin from an altitude of less than 500 feet [ meters]. It rolled over after hitting the landing field and was demolished.

     Lieutenant Giovannoli received a medal for his heroism in rescuing two men from the flaming wreckage of the Boeing “flying fortress” after it crashed in the army bomber tests at Wright Field, Dayton.

     The Wright Field hero was taking off for the Middletown, Penn., air station when his plane plunged him to death at Logan Field.

QUIZ TO BE BEGUN.

     The flier had arrived here yesterday.

     Lieutenant Colonel H.C.K. Nuhlenberg, air officer of the Third Corps Area and in command of Logan Field, said an Army Board of Inquiry would be summoned promptly to investigate the fatal crash.

     Nuhlenberg, who had just landed at the field himself, said Giovannoli had gotten his craft under way and turned back to fly over the field at a low altitude.

     The wing of Giovannoli’s plane wrenched off, Nuhlenberg said, just as the craft was coming out of the glide and starting a zoom to regain altitude.

—The Cincinnati Enquirer, Vol. XCV, No. 334, Monday, 9 March 1936,  at Page 7, Column 1

Lt. Robert K. Giovannoli

Lieutenant Giovannoli had been awarded the Soldier’s Medal and the Cheney Award for his heroic rescue of two men from the burning wreck of the Boeing Model 299, which had crashed on takeoff at Wright Field, 30 October 1935. His citation reads:

The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Soldier’s Medal to First Lieutenant Robert K. Giovannoli, United States Army Air Corps, for heroism, not involving actual conflict with an enemy, displayed at Wright Field, Dayton, Ohio, 30 October 1935. When a Boeing experimental bomber crashed and burst into flames, Lieutenant Giovannoli, who was an onlooker, forced his way upon the fuselage and into the front cockpit of the burning plane and extricated one of the passengers. Then upon learning that the pilot was still in the cockpit, Lieutenant Giovannoli, realizing that his own life was in constant peril from fire, smoke, and fuel explosions, rushed back into the flames and after repeated and determined efforts, being badly burned in the attempt, succeeded in extricating the pilot from an entrapped position and assisted him to a place of safety.

Robert Kinnaird Giovannoli was born at Washington, D.C., 13 March 1904, the second of two sons of Harry Giovannoli, a newspaper editor, and Carrie Kinnaird Giovanolli. His mother died when he was six years old.

Robert Giovannoli, 1925. (The Kentuckian)

Giovannoli graduated from Lexington High School at Lexington, Kentucky, in 1920 and then attended the University of Kentucky, where, in 1925, he earned a Bachelor of Science degree in Mechanical Engineering (B.S.M.E.). He was a member of the Phi Delta Theta (ΦΔΘ) and Tau Beta Phi (ΤΒΦ) fraternities, treasurer of the sophomore class, and president of the American Institute of Electrical Engineers. He was employed by the General Electric Company at Schenectady, New York.

Giovannoli enlisted in the United States Army in 1927. After completing the Air Corps Primary Flying School at Brooks Field, and the Advanced Flying School at Kelly Field, both in San Antonio, Texas, he was commissioned as a second lieutenant in the Air Corps Reserve, 20 October 1928. Lieutenant Giovannoli was called to active duty 8 May 1930. In 1933, he was assigned to a one year Engineering School at Wright Field. He then was sent to observe naval aircraft operations aboard USS Ranger (CV-4) in the Pacific Ocean. He had returned just a few days prior to the accident.

At the time of his death, Lieutenant Giovannoli had not yet been presented his medals.

First Lieutenant Robert Kinnaird Giovannoli was buried at the Bellevue Cemetery, Danville, Kentucky. In 1985, the Robert Kinnaird Giovannoli Scholarship was established to provide scholarships for students in mechanical engineering at the University of Kentucky College of Engineering.

The P-26, Air Corps serial number 32-414, was the last of three prototype XP-936 pursuits built by Boeing in 1932. Boeing’s chief test pilot, Leslie R. Tower, conducted the first flight of the type on 20 March 1932. Leslie Tower was one of the two men that Lieutenant Giovannoli had pulled from the burning Boeing 299.

The Boeing P-26 was a single-seat, single-engine monoplane. It was the first all-metal U.S. Army pursuit, but retained an open cockpit, fixed landing gear and its wings were braced with wire. The airplane was 23 feet, 7 inches (7.188 meters) long with a wingspan of 28 feet (8.534 meters). The empty weight of the prototype was 2,119 pounds (961.2 kilograms) and gross weight was 2,789 pounds (1,265.1 kilograms).

The first of three Boeing Model 248 prototypes, XP-26 32-412. (Boeing)

The Y1P-26 was powered by an air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney R-1340-21 (Wasp S2E), a single-row, nine-cylinder radial engine. The P-26A and P-26C were powered the Pratt & Whitney R-1340-27 (Wasp SE), while the P-26B used a more powerful, fuel-injected R-1340-33 (Wasp D2). Each of these engines were direct drive and had a compression ratio of 6:1. The engine was surrounded by a Townend Ring which reduced aerodynamic drag and improved engine cooling.

The R-1340-21 had a Normal Power rating of 600 horsepower at 2,200 r.p.m. at 6,000 feet (1,829 meters); 500 horsepower at 2,200 r.p.m. at 11,000 feet (3,353 meters); and 500 horsepower at 2,000 r.p.m. for takeoff. It required 87-octane gasoline. The –21 had a diameter of 3 feet, 3.44 inches (1.307 meters) and weighed 715 pounds (324 kilograms).

The R-1340-27 had a Normal Power and Takeoff power rating of 570 horsepower at 2,200 r.p.m., to 7,500 feet (1,524 meters), using 92-octane gasoline. The –27 was 3 feet, 7.25 inches (1.099 meters) long, 4 feet, 3.50 inches (1.308 meters) in diameter and also weighed 715 pounds (324 kilograms).

The R-1340-33 was rated at 575 horsepower at 2,200 r.p.m. to 10,000 feet (3,048 meters), and 600 horsepower at 2,120 r.p.m. for Takeoff, with 87-octane gasoline. It was 3 feet, 10.75 inches (1.187 meters) long, with the same diameter as the –27. It weighed 792 pounds (359 kilograms).

The engines drove a two-bladed, Hamilton Standard adjustable-pitch propeller.

The pursuit had a maximum speed of 227 miles per hour (365 kilometers per hour) at 10,000 feet (3,048 meters), and a service ceiling of 28,900 feet (8,809 meters).

As a pursuit, the P-26 was armed with two air-cooled Browning M1919 .30-caliber machine guns, synchronized to fire forward through the propeller arc.

Boeing built 136 production P-26s for the Air Corp and another 12 for export. Nine P-26s remained in service with the Air Corps at the beginning of World War II.

26 February–2 March 1949: A Boeing B-50A Superfortress, Air Force serial number 46-010, named Lucky Lady II, flew from Carswell Air Force Base, Fort Worth, Texas, and with inflight refueling, circumnavigated the Earth non-stop, landing back at Carswell after 94 hours, 1 minute. The bomber had traveled 23,452 miles (37,742 kilometers).

Lucky Lady II was the backup aircraft for this flight, but became primary when the first B-50, Global Queen, had to abort with engine problems. It was a standard production B-50A-5-BO (originally designated B-29D) with the exception of an additional fuel tank mounted in its bomb bay.

The aircraft commander was Captain James G. Gallagher, with 1st Lieutenant  Arthur M. Neal as second pilot. Captain James H. Morris was the copilot. In addition to the three pilots, the flight was double-crewed, with each man being relieved at 4-to-6 hour intervals. The navigators were  Captain Glenn E. Hacker and 1st Lieutenant Earl L. Rigor, and the radar operators were 1st Lieutenant Ronald B. Bonner and 1st Lieutenant William F. Caffrey. Captain David B. Parmalee was project officer for this flight and flew as chief flight engineer, with flight engineers Technical Sergeant Virgil L. Young and Staff Sergeant Robert G. Davis. Technical Sergeant Burgess C. Cantrell and Staff Sergeant Robert R. McLeroy were the radio operators. Gunners were Technical Sergeant Melvin G. Davis and Staff Sergeant Donald G. Traugh Jr.

Four inflight refuelings were required using the looped hose method. Two KB-29M tankers of the 43d Air Refueling Squadron were placed at air bases along the Lucky Lady II‘s route, at the Azores, Saudi Arabia, the Philippine Islands and Hawaiian Islands. The KB-29 flew above the B-50 and lowered a cable and drogue. This was captured by equipment on the bomber and then reeled in, bringing along with it a refueling hose. The hose was attached to the B-50’s refueling manifold and then fuel was transferred from the tanker to the bomber’s tanks by gravity flow.

Each refueling occurred during daylight, but weather made several transfers difficult. One of the two tankers from Clark Field in The Philippines, 45-21705, crashed in bad weather when returning to base, killing the entire 9-man crew.

On their arrival at Carswell, the crew of Lucky Lady II was met by Secretary of the Air Force W. Stuart Symington, Jr., General Hoyt S. Vandenberg, Chief of Staff of the Air Force, General Roger M. Ramey, commanding 8th Air Force, and Lieutenant General Curtis E. LeMay, Strategic Air Command. Each member of the crew was awarded the Distinguished Flying Cross. They also were awarded the Mackay Trophy for the most meritorious flight of the year.

At 11:25 a.m., 13 August 1950, B-50A 46-010, under the command of  Captain Warren E. Griffin, was on a maintenance test flight and returning to its base, Davis-Monthan AFB, Tucson, Arizona  when all four engines failed. Unable to reach the runways, Captain Griffin landed in the desert approximately two miles southeast. Though the landing gear were down, the bomber was severely damaged with all four propellers bent, the belly dented and its tail breaking off. The 11-man crew were uninjured except for the bombardier, 1st Lieutenant Theodore Hastings, who was scratched by cactus which entered the cockpit through the broken Plexiglas nose.

The Superfortress was damaged beyond economical repair and was stricken from the Air Force inventory (“written off”). The unrestored fuselage of Lucky Lady II is at the Planes of Fame Air Museum, Chino, California.

Jet Bomber Spans Nation in 3 Hours 46 Minutes

New Plane Averages 607.2 m.p.h. to Make Fastest Coast-to-Coast Journey on Record

     Washington, Feb. 8 (AP)—An arrow-shaped XB-47 jet bomber streaked through the stratosphere at an average speed of 607.2 miles an hour today in the fastest transcontinental flight ever made.

     The bomber, rated as “light” despite its 125,000 pounds, flew 2289 miles from Moses Lake (Wash.) Air Base to Andrews Field, Md., a few miles south of the capital, in 3h. 46m.

     The pace was 27 minutes shorter in time and 23 miles faster in average speed than the official record of 4h. 13m. at 584 m.p.h. established by Col. William H. Council [sic] in an F-80 Shooting Star two years ago.

     However, the Air Force will claim no record. The flight was not timed officially and it did not fly the recognized contest course. The recognized course—the one Col. Council flew—is Los Angeles to new York, 2464 miles.

     The XB-47 is a six-engine, swept wing bomber built by Boeing Airplane Co. at Seattle, known as the Stratojet, it is the Air Force’s first bomber designed for speeds in excess of 600 miles an hour.

     The XB-47 is the plane to which Air Force Secretary Symington referred last fall when he mentioned a jet bomber running away from jet fighters. Ten XB-47s are to be built at Boeing’s Wichita (Kan.) plant, where about half of all the B-29s were built during the war.

     Maj. Russell E. Schleeh, pilot, and Maj. Joseph W. Howell, co-pilot, both said the flight was strictly routine. They were comfortable in a new type flying suit being tested by the Materiel Command, used oxygen all the way, and navigated by radio compass on a great circle course which took them 20 miles south of Chicago.

     The first  part of the flight was at 32,000 feet. Later they moved up to 37,000 feet. The pressurized cabin was maintained at 23,000 feet. During one hour they covered 648 miles.

     In addition to six J-35 turbo-jet engines built by General Electric Co. at Lynn, Mass., which gave a total of 24,000 pounds of thrust, the Stratojet can use 18 rockets each capable of delivering 1000 pounds of thrust for a few seconds. The rockets were not carried today.

     The XB-47 carries a parachute in its tail to help it stop quickly.

Designed as a strategic bomber, the B-47 could fly higher and faster than jet fighters of the time, and it was also highly maneuverable. The XB-47 (Boeing Model 450) was flown by a two-man crew in a tandem cockpit. It was 107 feet, 6 inches (32.766 meters) long with a wingspan of 116 feet (35.357 meters). The top of the vertical fin was 27 feet, 8 inches (8.433 meters) high. The wings were shoulder-mounted with the leading edges swept at 35°.

The first prototype, 46-065, was powered by six General Electric J35-GE-7 axial flow turbojet engines in four pods mounted on pylons below the wings. The J35 was a single-spool, axial-flow turbojet engine with an 11-stage compressor and single-stage turbine. The J35-GE-7 was rated at 3,750 pounds of thrust (16.68 kilonewtons) at 7,700 r.p.m. (static thrust, Sea Level). The engine was 14 feet, 0.0 inches (4.267 meters) long, 3 feet, 4.0 inches (1.016 meters) in diameter and weighed 2,400 pounds (1,089 kilograms). (The second prototype, 46-066, was completed with J47 engines. 46-065 was later retrofitted with these engines.)

The XB-47 prototype had a maximum speed of 502 knots (578 miles per hour/930 kilometers per hour/0.80 Mach) at 15,000 feet (4,572 meters). The combat speed was 462 knots (532 miles per hour/856 kilometers per hour/0.70 Mach) at 35,000 feet (10,668 meters). The prototype’s empty weight was 74,623 pounds (33,848 kilograms), while its maximum takeoff weight was 162,500 pounds (73,709 kilograms). It required a ground run of 11,900 feet (3,627 meters), or 4,800 feet (1,463 meters) with JATO assist. The bomber could climb at a rate of 3,650 feet per minute (18.5 meters per second) at Sea Level, at combat weight and maximum power. The service ceiling was 37,500 feet (11,430 meters). The XB-47 carried 9,957 gallons (37,691 liters) of fuel. The combat radius was 1,175 nautical miles (1,352 statute miles/2,176 kilometers) with a 10,000 pound (4,536 kilogram) bomb load.

Planned armament (though the XB-47s were delivered without it) consisted of two .50-caliber machine guns in a tail turret, with 1,200 rounds of ammunition, and 10,000 pounds (4,536 kilograms) of bombs.

The Stratojet was one of the most influential aircraft designs of all time and its legacy can be seen in almost every jet airliner built since the 1950s: the swept wing with engines suspended on pylons, , mounted forward of the leading edge.

2,032 B-47s were built by Boeing Wichita, Douglas Tulsa and Lockheed Marietta. They served the United States Air Force from 1951 to 1977.

The very last B-47 flight took place 18 June 1986 when B-47E-25-DT, serial number 52-166, was flown from the Naval Air Weapons Center China Lake to Castle Air Force Base to be placed on static display.

XB-47 45-065 stalled while landing at Larson Air Force Base, near Moses Lake, Washington, 18 August 1951. The crew of three escaped uninjured. The airplane was damaged beyond repair. The second prototype, XB-47 46-066, is in the collection of the Air Force Flight Test Museum, Edwards Air Force Base, California.
