Pan American World Airways’ Boeing 707-121, N711PA, Clipper America, at Idlewild Airport, New York, 26 October 1958. (Pan American World Airways)
26 October 1958: Pan American World Airways opened the “Jet Age” with the first commercial flight of an American jet airliner. Pan Am’s Boeing 707-121 Clipper America, N711PA, departed New York Idlewild (IDL) on an 8 hour, 41 minute flight to Paris Le Bourget (LBG), with a fuel stop at Gander, Newfoundland (YQX). (The actual flight time was 7 hours.) The distance was 3,634 miles (5,848 kilometers). Aboard were 111 passengers and 11 crewmembers.
A Pan Am company publication explained the need for the stop at Gander:
The Jet could not be fully loaded with fuel before takeoff because of weight restrictions imposed at Idlewild. Fuel capacity of the jet is 17,398 gallons, allowing a cruising range of 4,400 miles. But with a full pay load of passengers, only 9,731 gallons could be taken aboard in New York.

The Boeing 707 was developed from the earlier Model 367–80, the “Dash Eighty”. It is a four-engine jet transport with swept wings and tail surfaces. The leading edge of the wings are swept at a 35° angle. The airliner had a flight crew of four: pilot, co-pilot, navigator and flight engineer. The 707-121 is 145 feet, 1 inch (44.221 meters) long with a wing span of 130 feet, 10 inches (39.878 meters). The top of the vertical fin stands 42 feet, 5 inches (12.929 meters) high. The 707 pre-dated the ”wide-body” airliners, having a fuselage width of 12 feet, 4 inches (3.759 meters).
The first versions were powered by four Pratt & Whitney Turbo Wasp JT3C-6 turbojet engines, producing 11,200 pounds of thrust (49,820 kilonewtons), and 13,500 pounds (60.051 kilonewtons) with water injection. This engine was a civil variant of the military J57 series. It was a two-spool axial-flow turbojet engine with a 16-stage compressor and 2 stage turbine. The JT3C-6 was 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighed 4,235 pounds (1,921 kilograms).
The airliner’s empty weight is 122,533 pounds (55,580 kilograms). Maximum take off weight (MTOW) is 257,000 pounds (116,573 kilograms). At MTOW, the 707 required 11,000 feet (3,352.8 meters) of runway to take off. Its maximum speed is 540 knots (1,000 kilometers per hour). It had a range of 2,800 nautical miles (5,185.6 kilometers).
The Boeing 707 was in production from 1958 to 1979. 1,010 were built. As of 2011, 43 707s were still in service.
Boeing delivered N711PA to Pan American on 17 October 1958. The airliner was named Clipper America, but was later renamed Clipper Mayflower. It was leased to Avianca (Aerovías Nacionales de Colombia S.A.) from 1960 to 1962. In April 1965 the 707 was upgraded to the –121B standard. This included a change from the turbojet engines to quieter, more powerful and efficient Pratt and Whitney JT3D-1 turbofans, producing 17,000 pounds of thrust. The wings were modified to incorporate changes introduced with the Boeing 720, and a longer tailplane installed. Pan Ayer of Panama purchased Clipper Mayflower 21 February 1975. It was later leased to Türk Hava Yolları, the Turkish national airline, and went on to serve with Air Asia Company Limited (an Air America aircraft service unit) and E-Systems. After 26 years of service, in August 1984 Clipper America was scrapped at Taipei.

26 September 2003: At 2:38 a.m., Friday, David Kim Hempleman-Adams, O.B.E., lifted off from the athletic field of Sussex Elementary School, Sussex, New Brunswick, Canada, in his Rozière balloon on a four-day transatlantic flight. Hempleman-Adams was in an open 7 feet × 3 feet (2.1 × 0.9 meters) wicker basket.

The balloon was built by Cameron Balloons, Ltd., Bristol, in 2000. It was a Cameron R-90, serial number 4751. The balloon was first registered 31 March 2000, as G-BYZX.
The R-90 is a Rozière balloon, which has separate chambers for helium and heated air. This allows the aeronaut to control the balloon’s buoyancy, but the hybrid type uses much less fuel than a hot-air balloon. The type is named after its inventor, Jean-François Pilâtre de Rozier. The Fédération Aéronautique Internationale places the Cameron R-90 in the free balloon sub-class AM-08, for mixed balloons with a volume of 2,200–3,000 cubic meters (77,692–105,944 cubic feet).
G-BYZX had a maximum takeoff weight of 2,654 kilograms (5,851 pounds).
Hempleman Adams had previously flown G-BYZX, then named Britannic Challenge, to the North Pole, on 3 June 2000. Following his transatlantic flight, he would use it to set a FAI World Record for Altitude of 12,557 meters (41,198 feet), 23 March 2004.
During the first day, Hempleman-Adams’ balloon gradually rose to an altitude of 8,000 feet (2,438 meters) as it drifted eastward. On the second day he was at 10,000 feet (3,048 meters), and on Day 3 he reached a peak of 14,000 feet (4,267 meters).
The weather was very cold, with rain and snow. Hempleman-Adams said that the average temperature during the flight was -12 °C. (10.4 °F.). Ice built up on the balloon’s envelope, increasing its weight. It became heavy enough that the balloon began to descend. Hempleman-Adams was unable to prevent the descent by using the propane burners to heat the air and increase buoyancy, and was forced to lighten the balloon by jettisoning six propane cylinders.
During the third day, the balloon was hit by the shock waves of a Concorde supersonic airliner as it passed overhead at 30,000 feet (9,144 meters). Hempleman-Adams felt a very abrupt, but fortunately, brief, descent as a result.
G-BYZX reached the southwestern tip of Ireland at 8:30 a.m., BST, on 29 September, completing the transatlantic phase of his flight. The balloon continued to drift eastward, and at 6 p.m. on 30 September, came to rest near Hambleton, Lancashire, England. The total duration of the flight was 83 hours, 14 minutes, 35 seconds.
Sir David Kim Hempleman-Adams, K.C.V.O., O.B.E., K.St.J., D.L., is an interesting guy. He is the first person to have completed the True Adventurer’s Grand Slam, by reaching the North and South Poles, the North and South Magnetic Poles, and to have climbed the highest mountains on each of the seven continents. The Fédération Aéronautique Internationale online database currently credits him with 49 world aviation records.

14–18 September 1984: Colonel Joseph W. Kittinger II, United States Air Force (Retired), lifted of from Caribou, Maine, at the extreme northeast corner of the United States, aboard Rosie O’Grady’s Balloon of Peace, a 3,000-cubic-meter Yost GB55 helium-filled balloon, registered N53NY. 86 hours later, he came rest at Montenotte, Italy, having completed the very first solo transatlantic balloon flight.
Kittinger established four Fédération Aéronautique Internationale (FAI) World Records for Distance, having travelled 5,703.03 kilometers (3,543.70 miles).¹ These records still stand.
This was not the first time Joe Kittinger had ascended in a balloon. The previous year he had set two FAI distance records, covering 3,221.23 kilometers (2,001.58 miles) from Las Vegas, Nevada to Farmersville, New York.² But he is best known for his historic high-altitude balloon flights. On 2 June 1957, Joe Kittinger rode the Project MAN-HIGH I balloon to an altitude of 97,760 feet (29,490 meters). One 16 August 1960, aboard Excelsior III, Kittinger reached 102,800 feet (31,333 meters). He then stepped out of the gondola and began the longest free-fall parachute descent attempted.
During the Vietnam War, Joe Kittinger flew 483 combat missions during three tours. He shot down one enemy MiG-21 fighter, and was later himself shot down. He was captured and held at the infamous Hanoi Hilton for 11 months.

Beryl Markham steps out of the cockpit of the Percival Vega Gull, probably late August 1936. (Library of Congress)
4–5 September 1936: At 6:50 p.m., British Summer Time, Beryl Markham departed RAF Abingdon, Oxfordshire, England, aboard a turquoise blue and silver Percival P.10 Vega Gull, registration VP-KCC. Her intended destination was New York City, across the Atlantic Ocean in America.
The airplane flown by Mrs. Markham, serial number K.34, was brand-new, built for John Evans Carberry (formerly, 10th Baron Carbery) for his entry in The Schlesinger air race from London, England, to Johannesburg, South Africa. He loaned the airplane to her for the transatlantic flight on condition that she would return it to England by mid-September, in time for the start of the race.

Designed by Edgar Percival and built by Percival Aircraft Limited at Gravesend, the P.10 Vega Gull was a four-place, single engine monoplane with fixed landing gear. Known as the K-series, it was a development of the previous D-series Gull Six. The airplane was 25 feet, 6 inches (7.772 meters) long with a wingspan of 39 feet, 6 inches (12.040 meters) and height of 7 feet, 4 inches (2.235 meters). The standard airplane had an empty weight of 1,740 pounds (789.25 kilograms) and loaded weight of 3,250 pounds (1,474.2 kilograms). K.34, the airplane flown by Markham, carried two auxiliary fuel tanks in the passenger compartment, for a total capacity of 255 gallons (965.3 liters).
The Vega Gull was powered by an air-cooled, normally-aspirated, 9.186 liter (560.573-cubic-inch-displacement) de Havilland Gypsy Six I, an inverted inline six-cylinder overhead valve (OHV) engine. The engine had a compression ratio of 5.25:1. It was rated at 184 horsepower at 2,100 r.p.m., and 205 horsepower at 2,350 r.p.m. for takeoff. The direct-drive engine turned a two-bladed Ratier variable-pitch propeller. The Gypsy Six I weighed 432 pounds (196 kilograms).
The Vega Gull had a cruising speed of 150 miles per hour (241 kilometers per hour) and a maximum speed of 174 miles per hour (280 kilometers per hour). The service ceiling was 17,000 feet (5,181.6 meters). Estimated range with the auxiliary fuel tank was 3,800 miles (6,115.5 kilometers).

John Carberry was a resident of Colony and Protectorate of Kenya so the new airplane received the civil registration marking, VP-KCC. It was named The Messenger.
Beryl Markham was an experienced airplane pilot who had most recently been employed as Chief Pilot, Air Cruisers Limited, owned by a French financier, François Dupré. She was certified both as a pilot and an aircraft mechanic, and had recently had her pilot’s license endorsed for “All Types.”

Mrs. Markham and the airplane were ready for the solo transoceanic flight by 1 September, but were delayed by bad weather, with worse forecast. Captain Percival had recommended that she start from RAF Abingdon because its 1 mile runway (1.6 kilometers) would give the overweight airplane a longer takeoff run.
By the 4th, however, she was impatient with waiting and decided to takeoff regardless of the weather. She arrived at the airfield at about 5:00 p.m. Her takeoff was delayed while the runway was cleared of a wrecked bomber that had been overturned by the high winds.
Because of the high winds, the Vega Gull was airborne in just 600 yards (550 meters).

From the start, Markham encountered heavy rain, low clouds, fog, and gale force winds. Almost immediately, her carefully-prepared chart was blown out of a cockpit window. She flew most of the distance at an altitude of about 2,000 feet (610 meters). If she climbed higher, the rain turned to ice. If she flew lower she was in danger of the winds forcing her into the sea below. She had hoped to have the light of a nearly full moon as she crossed the Atlantic at night but the weather was so bad that she flew by reference to her instruments for the entire crossing.
During the transatlantic flight the Percival Vega Gull was sighted by several ships which reported her position. Although the airplane had a cruising speed of 150 miles per hour (241 kilometers per hour), because of the headwinds, Markham estimated her rate of advance at just 90 miles per hour (145 kilometers per hour). With the airplane running on fuel from the final tank, which should have lasted 11 hours, the gauge indicated that it was being consumed at a higher rate. She estimated her position as nearing Newfoundland but with rain, clouds and fog, she was only able to see brief views of the ocean below.
The dawn broke through the clouds. The wind changed and I stopped being so silly. I wouldn’t have imagined that there was an expanse of desolation so big in the whole world as the waste of sky and water I saw go past me since I left Abingdon. . . It was fog, rain, sleet for hours on end. If I climbed it was sleet, if I dropped it was rain. If I skimmed the sea it was fog. I couldn’t see anything beyond my wingtips. . .
That tank, on which I was banking my all, didn’t last eleven hours. It lasted nine hours and five minutes. . . I watched that tank getting emptier and emptier and still saw nothing but sea and clouds and mist. . . I could see nothing to save me. Good old Messenger was going to stop any moment and I said to myself, “If I’m going to go, now is the time to get ready for it.” The only thing anywhere around was fog, great hefty banks of it. And then I saw the coast. The beautiful coast. I’ve never seen land so beautiful. . . But then the engine began to go “put, put, put.”
. . . I knew then that I had to come down and made for the beach. I couldn’t land there; there was nothing but great big rocks and Messenger and I would have been dashed to pieces. I went inland.
My engine was missing badly now. It was sheer agony to watch my petrol gauge . . . I peered around for a field to land on. I was still peering when the engine stopped.
—Beryl Markham, quoted in Straight on Till Morning, by Mary S. Lovell, St. Martin’s Press, New York, 1987, Chapter 9 at Pages 177–178.
The field turned out to be a peat bog at Baliene Cove on Cape Breton Island, Nova Scotia, Canada. The airplane nosed over in the soft surface. Beryl Markham struck her head and was briefly knocked unconscious. She soon climbed out of the damaged Vega Gull and was taken to a nearby farm where help soon arrived.
Beryl Markham did not reach her intended destination of New York City. But what she did accomplish was the first East-to-West solo crossing of the Atlantic Ocean by a woman. Although Amelia Earhart had flown solo across the Atlantic in her Lockheed Vega four years earlier, her crossing was West-to-East. Because of the prevailing weather patterns, the westerly crossing is considered much more difficult.
Beryl and The Messenger returned to England aboard the passenger liner RMS Queen Mary. Although the damage was repaired, it was not in time to compete in The Schlesinger. John Carberry sold VP-KCC to Dar-es-Salaam Airways. It was written off in Tanganyika in August 1937, and de-registered in March 1938.
Beryl Markham was a remarkable woman whose exploits are too great to touch on here. She wrote West with the Night, which was considered by author Ernest Hemingway to be “a bloody wonderful book.” She died at her home in Nairobi, Kenya, 3 August 1986, at the age of 83.

Breguet Br.19 TF Super Bidon Point d’Interrogation
1 September 1930: At 10:54 a.m., local time (09:54 G.M.T.), Dieudonné Costes and Maurice Bellonte ¹ took off from the Aéroport de Paris – Le Bourget, in a red Breguet Br.19 TF Super Bidon. Their destination was New York, non-stop across the North Atlantic Ocean. At 6:12:30 p.m., Eastern Daylight Time, 2 September (22:12:30 G.M.T.), they landed at Curtiss Field, Valley Stream, Long Island, New York. The two aviators had flown 5,913 kilometers (3,674 statute miles, 3,193 nautical miles) in a total elapsed time of 37 hours, 18 minutes, 30 seconds.
“Solid black line shows the course that Costes and Bellonte took from Paris. The broken line is the famous Lindbergh route.” (The Brooklyn Daily Times, Wednesday, 3 September 1930, Page 3, Columns 4–6)
More than 25,000 people, including Charles A. Lindbergh, were waiting at Valley Stream to welcome the two French aviators to America.
Breguet Br.19 TF Super Bidon Point d’Interrogation
The Breguet Br.19 TF Super Bidon was named Point d’Interrogation (“Question Mark”—?), because one of the flight’s sponsors—the Coty fragrance company—was a mystery. The airplane is a single-engine, two-place sesquiplane: a biplane with the span of the lower wing substantially shorter than the upper. It was a specially-built long-distance racer which had made its first flight two years earlier, on 23 July 1928. Since then it had been modified from the original TR configuration by lengthening the fuselage, increasing the wing span and the vertical gap between the wings, and increasing the fuel capacity.
The Br.19 TF was 10.718 meters (35 feet, 1.2 inches) long, with an upper wingspan of 18.300 meters (60 feet, 0.5 inches) and lower span of 11.496 meters (37 feet, 8.6 inches). The airplane’s height was 4.080 meters (13 feet, 4.6 inches). The total wing area was 61.940 square meters (666.717 square feet). The Super Bidon had an empty weight of 2,190 kilograms (4,828 pounds) and gross weight of 6,375 kilograms (14,054 pounds).
Costes and Bellonte at Boston, 1930 (Leslie Jones Collection, Boston Public Library)
Two main fuel tanks were placed between the engine and the crew’s cockpits. The tanks’ walls made up the fuselage surface in that area. The total fuel capacity was 5,570 liters (1,471 U.S. gallons), with two additional 166 liter (44 gallon) jettisonable tanks located under the lower wing. (These were removed just prior to takeoff.) The engine was provided with 220 liters of lubricating oil.
The Br.19 TF was powered by a liquid-cooled, normally-aspirated, 36.050 liter (2,199.892-cubic-inch-displacement) Société Française Hispano-Suiza 12Nb single-overhead-cam (SOHC) 60° V-12 engine, which produced 650 cheval-vapeur (641 horsepower) at 2,100 r.p.m. The direct-drive V-12 turned a two-bladed metal propeller.
The Super Bidon has a maximum speed of 250 kilometers per hour (155 miles per hour), and range of 6,700 kilometers (4,163 statute miles).
¹ Paris, Sept 1 (U.P.)—Dieudonné Coste and the Air Ministry have disagreed over the proper way to spell the famous flyer’s name.
Not long ago the flyer said he preferred to spell his name “Coste,” dropping the final”s.” which he used until a year ago. He signed autographs without the final “s” before departing for New York. The Air Ministry insisted, however, that the official spelling is “Costes.”
Coste’s name is pronounced to rhyme with “lost,” making the final letter silent.
Bellonte’s name is pronounced “Bell-ont,” to rhyme with “jaunt.”
