6 March 1961: The B-52H is the final version of the Boeing B-52 Stratofortress intercontinental strategic bomber. There are discrepancies as to the date of its first flight, with sources varying by as much as eight months. One very reliable source writes that the flight took place on 20 July 1960. A U.S. Air Force publication says that it was in March 1961, and another source (Boeing) says that it was 6 March 1961. An article in The Kansas City Times confirms the date:

B-52H IS TEST FLOWN

Initial Flight Is Made by Bomber at Wichita

     Wichita, March 6.(AP)—The first of this nation’s newest missile bombers, the global B-52H, took to the air in its initial flight today.

     A 6-man test crew of the Boeing Airplane company manned the production model super bomber, which is capable of flying 650 miles an hour over an 11,000-mile range.

     The bomber will carry four Douglas Skybolt missiles.

—The Kansas City Times, Vol. 124, No. 56, 7 March 1961, Page 21, Columns 7–8

The U.S. Air Force contracted 62 B-52H Stratofortresses, serial numbers 60-0001 through 60-0062, on 6 May 1960. A second group of 40, serials 61-0001 through 61-0040, were ordered later. All were built at the Boeing Wichita plant.

A fourth source identifies the aircraft in the photograph above, Boeing B-52H-135-BW Stratofortress 60-0006, (Boeing serial number 464-371) as the first B-52H to fly. The existence of a nice aerial portrait suggests that this may be correct.

The B-52H, like the B-52G, is a re-engineered aircraft, structurally different from the XB-52, YB-52, and B-52A–B-52F Stratofortress variants. It is lighter, carries more internal fuel, giving it a longer unrefueled range, and is strengthened for low-altitude flight. The B-52H is also equipped with quieter, more efficient turbofan engines.

The B-52H was developed to carry four Douglas GAM-87 Skybolt air-launched ballistic missiles on pylons mounted under the wings, inboard of the engines. The Skybolt was armed with a 1-megaton W-59 thermonuclear warhead. The program was cancelled, however, and the North American Aviation AGM-28 Hound Dog air-launched cruise missile was used instead. (Interestingly, the Hound Dog’s Pratt & Whitney J52-P-3 turbojet engine could be used to supplement the B-52’s takeoff thrust, and then refueled from the bomber’s tanks before being air-launched.)

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It was originally operated by a crew of six: two pilots, a navigator and a radar navigator, an electronic warfare officer, and a gunner. (The gunner was eliminated after 1991). The airplane is 159 feet, 4 inches (48.565 meters) long, with a wing span of 185 feet (56.388 meters). It is 40 feet, 8 inches (12.395 meters) high to the top of the vertical fin. The B-52H uses the vertical fin developed for the B-52G, which is 22 feet, 11 inches (6.985 meters) tall. This is 7 feet, 8 inches (2.337 meters) shorter than the fin on the XB-52–B-52F aircraft. The bomber has an empty weight of 172,740 pounds (78,354 kilograms) and its Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

The most significant difference between the B-52H and the earlier Stratofortresses is the replacement of the eight Pratt & Whitney J57-series turbojet engines with eight Pratt & Whitney Turbo Wasp JT3D-2 (TF33-P-3) turbofans, which are significantly more efficient. They are quieter and don’t emit the dark smoke trails of the turbojets. The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, a 14-stage compressor section (7-stage intermediate pressure, 7-stage high-pressure) and and a 4-stage turbine (1-stage high-pressure, 3-stage low-pressure). Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF33-P-3 is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (1,769 kilograms).

The B-52H has a cruise speed of 525 miles per hour (845 kilometers per hour). It has a maximum speed of 632 miles per hour (1,017 kilometers per hour) at 23,800 feet (7,254 meters)—0.908 Mach. The service ceiling is 47,700 feet (14,539 meters). The unrefueled range is 8,000 miles (12,875 kilometers). With inflight refueling, its range is limited only by the endurance of its crew.

The B-52H was armed with a 20 mm M61 Vulcan 6-barreled cannon in place of the four .50-caliber machine guns of the earlier variants.
The B-52H was armed with a 20 mm M61A1 Vulcan 6-barreled rotary cannon in place of the four .50-caliber machine guns of the earlier variants. The gun was removed after 1991.

The B-52H was armed with a 20mm M61A1 Vulcan six-barreled rotary cannon in a remotely-operated tail turret. The gun had a rate of fire of 4,000 rounds per minute, and had a magazine capacity of 1,242 rounds. After 1991, the gun and its radar system were removed from the bomber fleet. The flight crew was reduced to five.

The B-52H can carry a wide variety of conventional free-fall or guided bombs, land-attack or anti-ship cruise missiles, and thermonuclear bombs or cruise missiles. These can be carried both in the internal bomb bay or on underwing pylons. The bomb load is approximately 70,000 pounds (31,751 kilograms).

The first of 102 B-52H Stratofortresses entered service on 9 May 1961. The last one, 61-0040, was rolled out 26 October 1962. Beginning in 2009, eighteen B-52H bombers were placed in climate-controlled long term storage at Tinker Air Force Base, Oklahoma. As of December 2015, fifty-eight of the bombers remained in the active fleet of the United States Air Force and eighteen are assigned to the Air Force Reserve. In 2014, the entire fleet began a major avionics upgrade. B-52Hs remaining in the Air Force inventory will be upgraded with new engines, new radar, communications and navigation equipment, and will be redesignated B-52J. The B-52 is expected to remain in service until 2040.

60-0006, the first B-52H to fly, crashed while making a ground-controlled (GCA) approach to Wright Patterson Air Force Base, Dayton, Ohio, at 2:07 a.m., 30 May 1974. The bomber’s rudder and elevators failed. Although 60-0006 was destroyed, all seven airmen on board, Captains Charles Brown, Robert E. Smith, William G. Heckathorn, Paul C. Hoffman, 1st Lieutenants John D. Weaver, James R. Villines, and 2nd Lieutenant Robert E. Pace, survived the accident without serious injuries.

5 March 1936: At 4:35 p.m., Thursday afternoon, Vickers Aviation Ltd.’s Chief Test Pilot, Captain Joseph (“Mutt”) Summers, took off on the first flight of the Vickers-Supermarine Type 300, K5054, prototype of the legendary Supermarine Spitfire, at Eastleigh Aerodrome, Southampton, England. Landing after only 8 minutes, Summers is supposed to have said, “Don’t change a thing!”

The Vickers-Supermarine Type 300 was a private venture, built to meet an Air Ministry requirement ¹ for a new single-place, single-engine interceptor for the Royal Air Force. The airplane was designed by a team led by Reginald Joseph Mitchell, C.B.E., F.R.Ae.S., and was built at the Supermarine Aviation Works, Southampton, Hampshire, England.

R.J. Mitchell was famous for his line of Schneider Trophy-winning and world record-setting Supermarine racers of the late 1920s and early 1930s, the Supermarine S.4, S.5, S.6 and S.6B.² Mitchell was appointed Commander of the Most Excellent Order of the British Empire  (Civil Division) (CBE) in His Majesty’s New Year’s Honours, 2 January 1932, for “services in connection with the Schneider Trophy Contest.”

Reginald Joseph Mitchell, C.B.E., F.R.Ae.S.

The Vickers-Supermarine Type 300 was 29 feet, 11 inches (9.119 meters) long, with a wingspan of 36 feet, 10 inches (11.227 meters) and overall height of 12 feet, 8 inches (3.861 meters). The airplane’s wings had a distinctively ellipsoid shape. Their angle of incidence was 2.1° at the root and 0° at the tip, and there were 6.0° dihedral. The total area was 242.0 square feet (22.48 square meters). The Type 300’s empty weight was 4,082 pounds (1,852 kilograms) and its loaded weight was 5,332 pounds (2,419 kilograms).

K5054 was powered by an experimental Rolls-Royce Merlin C “ramp head” engine. This was a right-hand tractor, liquid-cooled, supercharged, 1,648.9-cubic-inch-displacement (27.04-liter) single overhead camshaft (SOHC) 60° V-12. Its company serial number was C9, and the number assigned to it by the Air Ministry, A111,139). The Merlin C had a Normal Power rating of 1,029 horsepower at 2,600 r.p.m. at an altitude of 11,000 feet (3,353 meters), with +6 pounds per square inch boost (0.41 Bar). The engine turned an Airscrew Co., Ltd., Watts-type two-bladed, fixed-pitch, compressed wood propeller through a gear reduction drive (possibly 0.420:1). An improved 1,035 horsepower Merlin F engine, serial number F21 (Air Ministry serial number A115,73 ), was later installed.

Interestingly, Rolls-Royce discovered that using exhaust stacks to direct the flow of gases rearward provided an additional 70 pounds of thrust, an increase of 7% over that provided by the propeller alone. Later testing of K5054 with “fish tail” exhaust stacks increased its top speed to about 360 miles per hour (579 kilometers per hour).

The Type 300 had a cruise speed of 311 miles per hour (501 kilometers per hour) at 15,000 feet (4,572 meters), and the prototype could reach that altitude in 5 minutes, 42 seconds. Its maximum speed was 349 miles per hour (562 kilometers per hour) at 16,800 feet (5,121 meters). K5054 had a service ceiling of 35,400 feet (10,790 meters).

A report summarizing the flight testing of K5054 stated, “The aeroplane is simple and easy to fly and has no vices.” Visibility was good, the cockpit was comfortable, and it was a stable gun platform.

On 22 March 1937, K5054’s engine lost oil pressure and the pilot made a belly landing on Marlesham Heath. The Spitfire was damaged, but it was repaired and returned to service.

The prototype Spitfire stalled on landing at RAE Farnborough, 4 September 1939. After several bounces on the runway, it nosed over. The pilot, Flight Lieutenant Gilbert Stanbridge (“Spinner”) White, was severely injured. He died 9 September.

K5054 was disassembled and scrapped.

The Air Ministry ordered the Spitfire Mk.I into production before K5054’s first flight, with an initial order for 310 airplanes. The first production fighter was delivered to the Royal Air Force 4 August 1938. Between 1938 and 1948, 20,351 Spitfires were built in 24 variants.

Captain Joseph Summers, C.B.E.

Captain Joseph Summers, C.B.E., was born 10 March 1904. He was the older brother of Group Captain Maurice Summers, who was also a test pilot for Vickers. In 1922, he married Miss Dulcie Jeanette Belcher at Sculcoates, Yorkshire. They would have several children.

In 1924, Summers received a short-service commission as an officer in the Royal Air Force. He trained as a pilot with No. 2 Flight Training Squadron, at RAF Duxford. He was hospitalized for six months, which delayed his training, but he graduated in 1924 and was assigned to No. 29 Fighter Squadron. Summers was considered to be an exceptional pilot, and with just six months’ operational experience, he was assigned as a test pilot at the Aircraft and Armaments Engineering Establishment (A&AEE) at RAF Martlesham Heath. He remained there for the reminder of his military service. In June 1929 he became a test pilot for Vickers Ltd. (Aviation Department). He became the company’s chief test pilot in 1932.

During his career as a test pilot, “Mutt” Summers made the first flights of 54 prototype aircraft, including the Spitfire, the Vickers Type 618 Nene-Viking, the Vickers Type 630 Viscount four-engine turboprop airliner, and the Vickers Type 667 Valiant, a four-engine jet bomber. He flew more than 5,600 hours in 366 different aircraft types.

“Mutt’s approach to test flying was much more in sympathy with the knee-pad than with the complicated automatic observers which nowadays are an indispensable part of test flying. He vigorously defended the feel of an aeroplane as measured by his hand or by the seat of his pants, and I believe was always suspicious of the scientific approach. . . One learned never to regard his criticism or advice lightly. In a world of science and instrumentation his judgement and horsesense often threw an unscientific but accurate light on some dark problem.”

—Sir George R. F. Edwards, O.M., C.B.E., F.S., D.L., Executive Director of the British Aircraft Corporation, quoted in Flight and Aircraft Engineer, No. 2357, Vol. 65, Friday, 26 March 1954, at Page 355, Column 2.

Joseph Summers, Esq., was appointed an Officer of the Most Excellent Order of the British Empire, Civil Division (O.B.E.), in His Majesty’s New Year’s Honours, Wednesday, 9 January 1946. He was promoted to Commander of the Most Excellent Order of the British Empire (Civil Division) (C.B.E.) in Her Majesty’s Coronation Honours, Monday, 1 June 1953.

Summers died 16 March 1954 at the age of 50 years.

Because of the underpowered J65-B-3 engine, there are no shock cones in the engine inlets. (U.S. Air Force via Jet Pilot Overseas)

Designed by the legendary Kelly Johnson, the XF-104 was a prototype Mach 2+ interceptor and was known in the news media of the time as “the missile with a man in it.”

There were two Lockheed XF-104 prototypes. Initial flight testing was performed with 083-1001 (USAF serial number 53-7786). The second prototype, 083-1002 (53-7787) was the armament test aircraft. Both were single-seat, single-engine supersonic interceptor prototypes.

The wing of the Lockheed XF-104 was very thin, with leading and trailing edge flaps and ailerons. (San Diego Air & Space Museum)

The XF-104 was 49 feet, 2 inches (14.986 meters) long with a wingspan of 21 feet, 11 inches (6.680 meters) and overall height of 13 feet, 6 inches (4.115 meters). The wings had 10° anhedral. The prototypes had an empty weight of 11,500 pounds (5,216 kilograms) and maximum takeoff weight of 15,700 pounds (7,121 kilograms).

The production aircraft was planned for a General Electric J79 afterburning turbojet but that engine would not be ready soon enough, so both prototypes were designed to use a Buick-built J65-B-3, a licensed version of the British Armstrong Siddeley Sapphire turbojet engine. The J65-B-3 was a single-shaft axial-flow turbojet with a 13-stage compressor section and 2-stage turbine. It produced 7,200 pounds of thrust (32.03 kilonewtons) at 8,200 r.p.m. The J65-B-3 was 9 feet, 7.0 inches (2.921 meters) long, 3 feet, 1.5 inches (0.953 meters) in diameter, and weighed 2,696 pounds (1,223 kilograms).

On 15 March 1955, XF-104 53-7786 reached a maximum speed of Mach 1.79 (1,181 miles per hour, 1,900 kilometers per hour), at 60,000 feet (18,288 meters).

XF-104 53-7786 was destroyed 11 July 1957 when the vertical fin was ripped off by uncontrollable flutter. The pilot, William C. Park, safely ejected.

Airship Hindenburg, D-LZ129, at Friedrichsafen, Germany
Airship Hindenburg, D–LZ 129, over Friedrichshafen, Germany, March 1936. (Unattributed)
Dr. Hugo Eckener

4 March 1936: The airship Hindenburg (D–LZ 129) made its first flight at Friedrichshafen, on the north shore of Lake Constance in southern Germany. In command was Hugo Eckener,¹ chairman of Luftschiffbau Zeppelin GmbH. There were 87 passengers and crew aboard.

The airship was operated by a flight crew of 40, with 12 stewards and cooks. There were 50 passenger sleeping berths in private cabins, with large public areas on the upper, “A” deck, with crew quarters, galley, a public bar and smoking lounge on the lower “B” deck. The ship’s control station was located in a gondola below the forward part of the hull.

The airship was designed by Ludwig Dürr. Its rigid structure was built of triangular-section duralumin girders (a specially heat-treated alloy of aluminum and copper, and anodized blue for corrosion protection). There were 15 ring frames and 36 longitudinals.

The airship’s control surfaces were operated by electric servo motors.

The Zeppelin’s covering was cotton fabric painted with a cellulose varnish which had been impregnated with aluminum powder, both to give it the silver color, but also to act as a reflector to protect the sixteen hydrogen-filled bouyancy gas bags contained inside from heat and ultraviolet light.

Hindenburg was 803 feet, 10 inches (245.008 meters) long, with a diameter of 135 feet, 1 inch (41.173 meters). Hindenburg had a gross weight of approximately 215,000 pounds (97,522 kilograms).

The huge airship was powered by four liquid-cooled, fuel-injected, 88.514 liter (5,401.478-cubic-inch-displacement) Daimler-Benz DB 602 50° V-16 diesel engines with 4 valves per cylinder and a compression ratio of 16:1. Mounted in a pusher configuration, the engines turned 19 foot, 8.4 inch (6.005 meter) diameter, four-bladed fixed-pitch wooden propellers through a 0.50:1 gear reduction. The DB 602 had a cruise power rating of 850 horsepower at 1,350 r.p.m. It could produce 900 horsepower at 1,480 r.p.m., and a maximum 1,320 horsepower at 1,650 r.p.m. (5 minute limit). The engines could be run in reverse. The DB 602 was 2.69 meters (8 feet, 10 inches) long, 1.02 meters (3 feet, 4 inches) wide and 1.35 meters (4 feet, 5 inches) high. Each engine weighed 1,976 kilograms (4,356 pounds).

Lift was provided by 16 hydrogen gas cells which were made of multiple layers of cotton fabric which was brushed with latex gelatin. These contained 7,062,000 cubic feet (199,974 cubic meters) of hydrogen with a lift capacity of 511,500 pounds (232,013 kilograms), nearly double the airship’s weight when fully loaded.

LZ 129 had a cruising speed of 76 miles per hour (122 kilometers per hour) and a maximum speed of 84 miles per hour (135 kilometers per hour).

Aérospatiale Concorde 001 first flight, at Toulouse, 2 March 1969, test pilot André Edouard Turcat.

2 March 1969: Just three weeks after the prototype Boeing 747, City of Everett, made its first flight at Seattle, Washington, the first supersonic airliner prototype, Aérospatiale-BAC Concorde Aircraft 001, registration F-WTSS, made its first flight, taking off from Runway 33 at the Aéroport de Toulouse-Blagnac, Toulouse, France.

On the flight deck were André Édouard Marcel Turcat, Henri Perrier, Michel Retif and Jacques Guinard.

The flight lasted 27 minutes. Throughout the flight, the “droop nose” and landing gear remained lowered.

Concorde was the only commercial airliner capable of cruising at supersonic speeds.

There were two Concorde prototypes (the British Aerospace Corporation built Concorde 002) followed by two pre-production developmental aircraft and sixteen production airliners.

Aérospatiale-BAC Concorde 001, F-WTSS. (Aérospatiale)

Concorde 001 is 51.80 meters (169 feet, 11.4 inches) long, with a wingspan of 23.80 meters (78 feet, 1 inch). Its fuselage has a maximum height of 3.32 meters (10 feet, 10.7 inches) and maximum width of 2.88 meters (9 feet, 5.4 inches) max internal height 1.96 m (6 feet, 5.2 inches). The prototype’s empty weight is 78,700 kilograms (173,504 pounds), and the maximum takeoff weight is 185,000 kilograms (407,855 pounds). (Pre-production and production Concorde weights and dimensions vary.)

The Concorde is powered by four Rolls-Royce/SNECMA Olympus 593 Mk.610 engines. The Mk. 610 is a two-spool, axial-flow turbojet with afterburner. The compressor section as 14 stages (7 low- and 7 high-pressure stages). Two-stage turbine has 1 high- and 1 low-pressure stage. The engine has a maximum continuous power rating of 28,800 pounds of thrust (128.11 kilonewtons). It is rated at 37,080 pounds (164.94 kilonewtons) for takeoff (5 minute limit). During takeoff, the afterburners produce approximately 20% of the total thrust. The Olympus 593 Mk.613 is 1.212 meters (3.976378 feet) in diameter, 4.039 meters (13.251312 feet)long, and weighs 3,175 kilograms (7,000 pounds).

Production Concordes were certified for a maximum operating cruise speed of Mach 2.04, and a maximum operating altitude of 60,000 feet (18.288 meters). The maximum range 3,900 was nautical miles (4,488 statute miles/7,223 kilometers).

Concorde 001 made 397 flight during flight testing. It accumulated a total of 812 hours, 19 minutes of flight time, of which 254 hours, 49 minutes were supersonic.

Today, Concorde 001 is displayed at the Musée de l’Air et de l’Espace, Aéroport de Paris – Le Bourget.
