26 September 2008: Yves Rossy flew across the English Channel, 22 miles (35 kilometers) in 13 minutes, using his jet-powered wing. At 8,000 feet (2,440 meters) over Calais he jumped from an airplane and aimed for the cliffs of Dover. His only means of steering was by moving his head. After flying at speeds of 120 miles per hour (193 kilometers per hour), he parachuted to the ground at Dover.
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.
26 September 1958: Lieutenant Colonel Victor Leonard Sandacz, with Kenneth G. Wolf, flew a Boeing B-52D Stratofortress from the 28th Bombardment Wing, Heavy, twice around a triangular circuit from Ellsworth Air Force Base, Rapid City, South Dakota, to Douglas, Arizona, Newberg, Oregon, and back to Rapid City. He established a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 10,000 Kilometers Without Payload with an average speed of 902.369 kilometers per hour (560.706 miles per hour).¹ Sandacz’s B-52 made two circuits in 11 hours, 9 minutes.
A second B-52D, flown by Captain Cholett Griswold and E.V. Godfrey, made a single circuit, setting an FAI World Record for Speed Over a Closed Circuit of 5,000 Kilometers Without Payload, averaging 961.867 kilometers per hour (597.676 miles per hour).² Griswold’s B-52 competed the course in 5 hours, 11 minutes, 49 seconds.
Observers from the National Aeronautic Association were aboard each bomber.
26 September 1927: Flight Lieutenant Sidney Norman Webster, A.F.C., of the Royal Air Force High-Speed Flight, won the 1927 Schneider Trophy Race, flying a Supermarine S.5 float plane, number N220.
The course consisted of seven laps of a 50-kilometer course at Venice, Italy. Webster completed the race in 46 minutes, 20.3 seconds, averaging 281.656 miles per hour (453.281 kilometers per hour). He established a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 Kilometers.¹
Webster’s teammate, Flight Lieutenant Oswald Worsley, flying S.5 N219, placed second with a time of 47:46.7 and average speed of 272.91 miles per hour (439.21 kilometers per hour).
The Supermarine S.5 was designed by Reginald Mitchell, who would later design the famous Supermarine Spitfire fighter. N220 was a single-place, single-engine, low-wing monoplane equipped with pontoons for landing and taking off on water. The airplane was of all metal construction, primarily duralumin (a hardened alloy of aluminum and copper). The airplane used surface radiators in the skin of the wings for engine cooling.
The S.5 had a length of 24 feet, 3½ inches (7.404 meters), wingspan of 26 feet, 9 inches (8.153 meters) and height of 11 feet, 1 inch (3.378 meters). The S.5’s empty weight was 2,680 pounds (1,216 kilograms) and gross weight was 3,242 pounds (1,471 kiograms).
Webster’s Supermarine S.5 was powered by a water-cooled, naturally-aspirated 1,461.135-cubic-inch-displacement (23.943 liter) D. Napier and Son, Ltd., Lion Mk.VIIB, serial number 63106, a double-overhead camshaft (DOHC) twelve-cylinder engine with three banks of four cylinders. This was called a “Triple-Four,” “W-12,” or “broad arrow” configuration. The Napier Lion had an included angle of 60° between each cylinder bank.
The Mk.VIIB had four valves per cylinder and a compression ratio of 10:1. It produced 875 horsepower at 3,300 r.p.m. The Lion VIIB drove a two-bladed fixed-pitch propeller through a gear reduction unit with a ratio of 0.765:1. (Worsley’s Supermarine S.5, N219, was equipped with a 900 horsepower direct-drive Mk.VIIA.) The engine used a mixture of 75% gasoline, 25% benzol, and 0.22% “T.E.L. dope” (tetraethyl lead) additive. The Napier Lion Mk.VII was 5 feet, 6¼ inches (1.683 meters) long, 3 feet, 2½ inches (0.978 meters) wide and 2 feet, 10½ inches (0.876 meters) high. The geared Mk.VIIB was heavier than the direct drive Mk.VIIA, and weighed 920 pounds (417 kilograms).
The Supermarine S.5 had a maximum speed of 319.57 miles per hour (514.3 kilometers per hour).
“Webbie” Webster had been awarded the Air Force Cross on 2 January 1922. He received a second award, signified by a “bar” added the the ribbon of his medal, 11 October 1927:
11th October, 1927.
The KING has been graciously pleased to approve the award of a Bar to the Air Force Cross held by Flight Lieutenant Sidney Norman Webster, A.F.C., in recognition of his achievement winning the recent “Schneider Cup” Air Race.
In January 1946, Air Commodore Webster was appointed Commander of the Most Excellent Order of the British Empire. He was promoted to Air Vice Marshal in 1949 and retired from the Royal Air Force 12 August 1950.
Air Vice Marshal Sidney Norman Webster, C.B.E., A.F.C. and Bar, Royal Air Force, died 5 April 1984 at the age of 83 years.
At the Aero Club of America Meet on 26 September 1911, at the Nassau Boulevard Aerodrome on Long Island, New York, Lieutenant Thomas DeWitt Milling set a world endurance record of 1 hour, 54 minutes, 42.6 seconds with two passengers, for which he was awarded the Rodman Wanamaker Endurance Trophy.
The trophy is on display at the National Museum of the United States Air Force.
