18 November 1966: On Flight 175 of the research program, Major William J. (“Pete”) Knight, U.S. Air Force, flew the newly-modified North American Aviation X-15A-2, 56-6671, to Mach 6.33 (4,261 miles per hour/6,857 kilometers per hour) at 98,900 feet (30,245 meters). This is just 11 years, to the day, since Pete Everest made the first powered flight in the Bell Aircraft Corporation X-2 rocketplane, with more than 6 times an increase in speed.
On this date, NASA made an attempt to launch two X-15s, -671 and -672, using the NB-52A 52-003 and NB-52B 52-008. However -672, the number three ship, had to abort the mission.

Balls 8, the NB-52B, flown by NASA test pilot Fitz Fulton and Colonel Joe Cotton, USAF, carried 56-6671 to the launch point over Mud Lake, Nevada, approximately 200 miles to the north of Edwards AFB. (This was the lake where -671 was severely damaged in an emergency landing, 9 November 1962. It was returned to North American to be rebuilt to the X-15A-2 configuration and returned to flight operation 19 months later.)
At 1:24:07.2 p.m. local time, Pete Knight and the X-15 were dropped from the pylon under the right wing of the B-52. He ignited the Reaction Motors XLR99-RM-1 and began to accelerate with its 57,000 pounds of thrust (253.549 kilonewtons).
Since this was to be a high temperature test flight, it was planned to fly no higher than 100,000 feet (30,480 meters). The denser atmosphere would result in greater aerodynamic heating of the rocketplane.
With the two external propellant tanks carrying an additional 1,800 gallons (6,814 liters) of liquid ammonia and liquid oxygen, the engine ran for 2 minutes, 16.4 seconds. The rocketplane had accelerated to Mach 2. The external tanks emptied in about 60 seconds and were jettisoned. The tanks were equipped with parachutes. They were recovered to be reused on later flights.
The X-15, now about 25,000 pounds (11,340 kilograms) lighter and without the aerodynamic drag of the tanks, continued to accelerate. At its highest speed, the rocketplane was travelling approximately 6,500 feet per second (1,981 meters per second), more than twice as fast as a high-powered rifle bullet. Its surface temperatures exceeded 1,200 °F. (649 °C.)
Knight landed the X-15 on Rogers Dry Lake at Edwards Air Force Base. The duration of this flight had been 8 minutes, 26.8 seconds.

18 November 1955: Major Frank Kendall Everest, Jr., USAF, makes the first powered flight in the Bell X-2 research rocketplane, 46-674, at Edwards AFB, California. The rocketplane was airdropped from a Boeing EB-50D Superfortress, 48-096. Only one 5,000-lb. thrust rocket tube ignited, but that was enough to accelerate “Pete” Everest to Mach 0.992 (655.4 miles per hour/1,054.5 kilometers per hour) at 35,000 feet (10,668 meters).
The X-2 was a joint project of the U.S. Air Force and NACA (the National Advisory Committee on Aeronautics, the predecessor of NASA). The rocketplane was designed and built by Bell Aircraft Corporation of Buffalo, New York, to explore supersonic flight at speeds beyond the capabilities of the earlier Bell X-1 and Douglas D-558-II Skyrocket.
In addition to the aerodynamic effects of speeds in the Mach 2.0–Mach 3.0 range, engineers knew that the high temperatures created by aerodynamic friction would be a problem, so the aircraft was built from stainless steel and K-Monel, a copper-nickel alloy.
The Bell Aircraft Corporation X-2 was 37 feet, 10 inches (11.532 meters) long with a wingspan of 32 feet, 3 inches (9.830 meters) and height of 11 feet, 10 inches (3.607 meters). Its empty weight was 12,375 pounds (5,613 kilograms) and loaded weight was 24,910 pounds (11,299 kilograms).

The X-2 was powered by a throttleable two-chamber Curtiss-Wright XLR25-CW-1 rocket engine that produced 2,500–15,000 pounds of thrust (11.12–66.72 kilonewtons)
Rather than use its limited fuel capacity to take off and climb to altitude, the X-2 was dropped from a modified heavy bomber as had been the earlier rocketplanes. A four-engine Boeing B-50D-95-BO Superfortress bomber, serial number 48-096, was modified as the drop ship and redesignated EB-50D.
The launch altitude was 30,000 feet (9,144 meters). After the fuel was exhausted, the X-2 glided to a touchdown on Rogers Dry Lake at Edwards Air Force Base.

Pete Everest joined the United States Army Air Corps shortly before the United States entered World War II. He graduated from pilot training in 1942 and was assigned as a P-40 Warhawk pilot, flying combat missions in North Africa, Sicily and Italy. He was credited with shooting down two German airplanes and damaging a third.
Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations where he shot down four Japanese airplanes. He was himself shot down by ground fire in May 1945. Everest was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war.

After the war, Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California. At Edwards, he was involved in nearly every flight test program, flying the F-88, F-92, F-100, F-101, F-102, F-104 and F-105 fighters, the XB-51, YB-52, B-57 and B-66 bombers. He also flew the pure research aircraft, the “X planes:” the X-1, X-1B, X-2, X-3, X-4 and X-5. Pete Everest flew the X-1B to Mach 2.3, and he set a world speed record with the X-2 at Mach 2.9 (1,957 miles per hour, 3,149.5 kilometers per hour) which earned him the title, “The Fastest Man Alive.”

Frank Everest returned to operational assignments and commanded a fighter squadron, two combat crew training wings, and was assigned staff positions at the Pentagon. On 20 November 1963, Colonel Everest, commanding the 4453rd Combat Crew Training Squadron, flew one of the first two operational McDonnell F-4C Phantom II fighters from the factory in St. Louis to MacDill Air Force Base. In 1965, Pete Everest was promoted to the rank of brigadier general. He was commander of the Aerospace Rescue and Recovery Service. He retired from the Air Force in 1973 after 33 years of service. General Everest died in 2004.

14–18 November 1932: Amy Johnson, CBE, (Mrs. James A Mollison) flew her new de Havilland DH.80A Puss Moth, c/n 2247, registration G-ACAB, from Lympne Aerodrome, London, England, to Cape Town, South Africa, a distance of approximately 6,300 miles (10,140 kilometers) in a total elapsed time of 4 days, 6 hours, 54 minutes. This broke the previous record which had been set by her husband, Jim Mollison, by 10 hours, 28 minutes.
A contemporary news article described the event:
FLIGHT, November 24, 1932
MRS. MOLLISON’S FINE FLIGHT
Beats her Husband’s Cape Record by 10½ Hours
THERE are few, we think, who will not admit that Mrs. J.A. Mollison (Miss Amy Johnson) has accomplished a really remarkable feat in her latest flight—from England to Cape Town in 4 days 6 hr. 54 min., thus beating her husband’s previous record for the same journey of 4 days 17 hr. 22 min. by 10 hr. 28 min.
Not only is the flight a magnificent achievement as far as the time taken is concerned, but as a feat of endurance, pluck, good piloting and navigation, it must be placed foremost in the list of great flights.
Throughout the flight Mrs. Mollison had had only 5 hours’ sleep!
As reported in last week’s issue of FLIGHT, Mrs. Mollison set out from Lympne, in her D.H. “Puss Moth” (“Gipsy Major”), Desert Cloud, at 6.37 a.m. on November 14, and at 7.30 p.m. arrived at Oran, on the North African coast, 1,100 miles distant. She made an hour’s stop to refuel en route at Barcelona, and after a halt of 4 hours at Oran she started off on a night flight across the Sahara Desert towards Gao and Niamey.
At this stage some anxiety was felt owing to the absence of news concerning her progress for over 24 hours. Then came the news that she had landed safely at Gao (some 1,300 miles from Oran) at noon, November 15—having thus successfully accomplished a most difficult flight across the desert, without landmarks, at night. After a short stop for refuelling Mrs. Mollison left for Duala, but after flying for about an hour she noticed that her tanks were almost empty. She at once returned to Gao and found that they had put in only 10 galls. instead of 42 galls.!
After this irritating delay she proceeded once more, arriving safely at Duala in the evening, and continuing, after a short halt, towards Loanda. On this stage, during the night, the oil circulation caused her some trouble, and so she landed the next morning at Benguela (Port. W. Africa) to set matters aright.
Fortunately, the trouble was not serious—probably a portion of the Sahara in the filters—and she was able to proceed after a delay of some 9 hours. A halt to refuel was made at Mossamedes in the evening of November 17 and then came another night flight on the final stage of her journey.
Meanwhile, news of her start on the last hop reached Capetown, and from midnight November 17–18, huge crowds made their way to the Municipal aerodrome—although Mrs. Mollison could not possibly arrive much before midday. There were, therefore, several thousand people on the aerodrome by the time she arrived.
Mrs. Mollison appeared somewhat unexpectedly, from inland, shortly after 3 p.m., and it was not until the machine was about to land that the crowd realised that it was the Desert Cloud. She landed at 3.31 p.m. (1.31 p.m. G.M.T), and immediately the cheering crown broke down the barriers and surrounded the machine. It was some time before she could get out of her machine, but eventually she was got into a car, and before driving away she waved to the crowd and said: “Thank you very much for your great welcome. I said I would come back, and I have done so. It is really too kind of you to give me such a welcome.”
Safely inside the aerodrome building, Mrs. Mollison spoke over the telephone to Mr. Mollison, after which she was taken to some friends, where she could obtain some well-earned sleep.

MRS. MOLLISON’S FINE FLIGHT
(Concluded from page 1133)
Needless to say, Mrs. Mollison has received numerous messages of congratulation, amongst which were the following: —From H.M. the King: “Please convey to Mrs. Mollison hearty congratulations on her splendid achievment. I trust that she is not too exhausted. —George, R.I.”
From Lord Londonderry, Secretary of State for Air: “On behalf of the Air Council I congratulate you most warmly on the successful completion of your magnificent flight.”
Messages were also sent by the Royal Aero Club and Royal Aeronautical Society, Lord Wakefield, etc.
Mr. A.E. Whitelaw, the Australian philanthropist—who gave Mr. Mollison £1,000 in recognition of his Australia flight—is presenting a cheque for £1,000 to Mrs. Mollison in recognition of her achievement.

The de Havilland Aircraft Co., Ltd., DH.80A Puss Moth was a single-engine high-wing monoplane with an enclosed cabin for a pilot and two passengers. It was constructed of a tubular steel frame covered with doped fabric. The airplane was 25 feet (7.620 meters) long with a wingspan of 36 feet, 9 inches (11.201 meters) and height of 6 feet, 10 inches (2.083 meters). The Puss Moth had an empty weight of 1,265 pounds (574 kilograms) and gross weight of 2.050 pounds (930 kilograms).
G-ACAB was powered by a 373.71-cubic-inch-displacement (6,124 cubic centimeters) air-cooled de Havilland Gipsy Major I inverted, inline 4-cylinder engine with a compression ratio of 5.25:1. It produced 120 horsepower at 2,100 r.p.m and 130 horsepower at 2,350 r.p.m. The engine weighed 306 pounds (138.8 kilograms).
The DH.80A had a cruise speed of 95 miles per hour (153 kilometers per hour) and maximum speed of 108 miles per hour (174 kilometers per hour). The airplane had a service ceiling of 17,000 feet (5,182 meters). The standard DH.80A had a range of 430 miles (692 kilometers), but The Desert Cloud had additional tanks which increased its range to over 2,000 miles (3,219 kilometers).
De Havilland built 284 DH.80A Puss Moths between 1929 and 1933. Only eight are known to exist. G-ACAB, then owned by Utility Airways, Ltd., was destroyed in a hangar fire at Hooton Park, Cheshire, 8 July 1940.
Amy Johnson flew this de Havilland DH.80A Puss Moth, G-ACAB, The Desert Cloud, from England to South Africa, 14–18 November 1932. She made the return flight the following month. (Arch. B. Bambeau via Fan d’ Avions)

18 November 1930: The prototype Boeing XP-9, Air Corps serial number A.C. 28-346, a single-seat, single-engine monoplane pursuit, made its first flight at Wright Field, Ohio.
This was Boeing’s first semi-monocoque aircraft, built of a sheet dural skin over metal formers. The Army Air Corps issued the contract 29 April 1928 and the aircraft was completed in September 1930, then shipped by railroad to the Army test base.
The XP-9 (Boeing Model 96) was a single-place, single-engine high-wing monoplane with fixed landing gear. It was 25 feet, 1.75 inches (7.665 meters) long. with a wingspan of 36 feet, 6 inches (11.125 meters) and height of 7 feet, 10.25 inches (2.394 meters). The prototype’s empty weight was 2,669 pounds (1,211 kilograms) and its maximum takeoff weight was 3,623 pounds (1,643 kilograms).
The pursuit prototype was powered by a pressurized-liquid-cooled, supercharged, 1,570.381-cubic-inch-displacement (25.734 liter) Curtiss Super Conqueror SV-1570-C dual-overhead camshaft (DOHC) 60° V-12 engine with 4 valves per cylinder. This engine was rated at 600 horsepower at 2,400 r.p.m. It weighed 920 pounds (417 kilograms).
Boeing Model 96, XP-9.
The airplane had a maximum speed of 213 miles per hour (343 kilometers per hour). The service ceiling was 26,800 feet (8,169 meters). Armament was a combination of two machine guns, either one .30-caliber and one .50-caliber, or two .50 caliber, mounted one each side of the fuselage, firing forward.
The placement of the single high wing seriously restricted the pilot’s vision, making landings very dangerous. The airplane was highly unstable in flight. Increasing the size of the tail surfaces did little to improve this. After just 15 flight hours, the XP-9 was permanently grounded and was used as an instructional airframe.
The performance and handling of the XP-9 was considered to be so poor that an option to buy five pre-production models was canceled.
The XP-9’s sole redeeming quality was its method of construction, which has been almost universal since that time.
Flying Tiger Line’s Boeing 707-349C N322F. (Flying Tiger Line Pilots Association)
14–17 November 1965: Captains Fred Lester Austin, Jr., and Harrison Finch, two retired Trans World Airlines pilots, took off from Honolulu on a 26,230-mile (42,213 kilometer), 57 hour, 27 minute flight around the world—from Pole to Pole!
The pair leased a brand new Boeing 707-349C, c/n 18975, registered N322F, from Flying Tiger Line. Nick-named Pole Cat, the airplane was crewed by a total of five pilots, all rated captains. In addition to Austin and Finch, there were Captain Jack Martin, Chief Pilot of Flying Tigers Line; Captain Robert N. Buck, TWA; and Boeing Senior Engineering Test Pilot James R. Gannett. Three navigators and three flight engineers completed the flight crew. John Larsen, TWA’s chief navigator, did most of the planning and the other two navigators and all three flight engineers were Flying Tiger Line employees.
COL Willard F. Rockwell, Sr.
Most of the cost of the flight was paid for by Colonel Willard F. Rockwell, Sr., founder of the Rockwell Corporation, who was one of 27 passengers aboard. The airliner was equipped with an experimental Litton Systems Inertial Navigation System (INS) and the very latest Single Side Band (SSB) communications equipment from Collins Radio.
The flight departed HNL and flew north to the North Pole, then south to London Heathrow, where they stopped for fuel. Unexpected runway restrictions limited the 707’s takeoff weight, so they had to make an extra fuel stop at Lisbon, Portugal before flying to Buenos Aires, Argentina. After another fuel stop there, they continued south, circled the South Pole four times, then headed north to Christchurch, New Zealand. From there, they continued on to Honolulu.
Total elapsed time for the flight was 62 hours, 27 minutes, 35 seconds with just under 5 hours on the ground.
Flying Tiger line’s Boeing 707-349C, N322F.
Flying Tiger Line’s Boeing 707-349C (an airline-specific variant of the 707-320C) was a “combi” that could be configured to carry passengers and/or cargo. The –320 series was a stretched version of the original 707-120 airliner, with longer, redesigned wings and tail plane, as well as a taller vertical fin for increased stability during low-speed flight. It was operated by a flight crew of four on international flights.
The 707-320 series was 152 feet, 11 inches (46.609 meters) long with a wingspan of 145 feet, 9 inches (44.425 meters) and overall height of 42 feet, 5 inches (12.929 meters). It had an empty weight of 146,400 pounds (66,406 kilograms) and a maximum takeoff weight of 333,600 pounds (151,318 kilograms).
The –320 was powered by four Pratt & Whitney Turbo Wasp JT3D-3 or JT3D-7 turbofan engines which produced 18,000 and 19,000 pounds of thrust, each, respectively. This engine was a civil variant of the military TF33 series. The JT3D-7 was a two-spool axial-flow turbojet engine with a 2-stage fan, 14-stage compressor (7 intermediate-, 7 high-pressure stages) and 4-stage turbine (1 high- and 3 low-pressure stages). The JT3D-7 had a maximum power rating of 19,285 pounds of thrust at 10,300 r.p.m. N2, (five-minute limit). The engine was 136.64 inches ( meters) long, 53.00 inches ( meters) wide and 56.00 inches ( meters) high, and weighed 4,340 pounds ( kilograms).
At MTOW, the 707-320 required 10,840 feet (3,304 meters) of runway for takeoff. 15 knots slower than a 707-120, the –320 had a maximum speed of 480 knots (552 statute miles per hour/889 kilometers per hour). The airliner’s range with maximum fuel was 5,750 nautical miles (6,617 statute miles/10,649 kilometers).
Boeing built a total of 1,010 707s. Of these, 337 were –320Cs. N322F was delivered to Flying Tiger Line 27 September 1965. It was sold to Caledonian Airways in 1968 and registered as G-AWTK. In 1970, Caledonian merged with British United and became British Caledonian. 18975 was then registered as G-BDCN, and named County of Renfrew. It was sold to TAAG Angola Airlines in 1977. The African cargo line registered 18975 as D2-TAC, D2-TOB and D2-TOI. Internet records list it as “written off” 15 February 1988.
