Adjutant Jean Pie Hyacinthe Paul Jérôme Casale, Aéronautique Militaire, circa 1917

14 June 1919: Sous Lieutenant Jean Pie Hyacinthe Paul Jérôme Casale took off from Issy-les-Moulineaux, France, to set a Fédération Aéronautique Internationale (FAI) World Record for Altitude. Flying a Nieuport-Delage chasseur (an aircraft type we now know as a fighter), he reached an altitude of 9,520 meters (31,234 feet). ¹ At that altitude, he was subjected to air temperatures of -50 °C. (-58 °F.). Casale landed at Villacoublay after a flight of approximately two hours.

Casale’s chasseur was a Nieuport-Delâge Ni-D 29 C.1, a single-place, single-engine, two-bay biplane.  The airplane was 6,50 meters (21.3255 feet) long with a wing span of 9,70 meters (31.8241 feet). The total wing area was 26,85 square meters (289.01099 square feet). The fighter had an empty weight of 740 kilograms (1,631.4 pounds) and gross weight of 1,100 kilograms (2425.085 pounds).

The airplane was powered by a water-cooled, turbosupercharged, 18.473 liter (1,127.29-cubic-inch displacement) right-hand tractor Hispano-Suiza 8Fb single overhead cam (SOHC) 90° V-8 engine. The engine was modified with the installation of a Rateau turbosupercharger to increase its output to more than 300 chaval vapeur. This was a direct-drive engine, and turned a two-bladed-fixed pitch propeller. The engine was 1.32 meters (4 feet, 4 inches) long, 0.89 meters (2 feet, 11 inches) wide, and 0.88 meters (2 feet, 10½ inches) high. It weighed 256 kilograms (564 pounds).

Engine cooling was provided by Lamblin cylindrical radiators mounted under the lower wing.

Pushing up World’s Height Record

Not satisfied with his height record of last week Lieut. Casole [sic] on June 14 took his Nieuport up to 10,100 metres (33,330 feet) during a flight from Villacoublay which lasted 1 hr. 55 mins. As in his previous flights, he used a Nieuport, fitted with a 300 h.p. Hispano-Suiza motor. His previous highest was 9,500 metres (31,350 ft.) and not 51,350 ft., as a printer’s error made it appear in our last issue.

  1. What about Hypoxia? Did he have supplemental oxygen or lungs that Reinhold Messier would envy? One wonders if man even knew about the dangers in that year. Intrepid Explorer, Sous Lt. Casale!
