18 September 1919: Curtiss Engineering Corporation test pilot Roland Rohlfs set a Fédération Aéronautique Internationale (FAI) World Record for Altitude when he flew a Curtiss 18T-2 Wasp triplane, U.S. Navy Bureau of Aeronautics serial number A3325, to an altitude of 9,577 meters (31,421 feet) over Roosevelt Field, Long Island, New York.¹ Contemporary sources, however, reported that Rohlfs’ peak altitude was 34,610 feet (10,549 meters).
This record broke Rohlfs’ previous FAI World Record for Altitude of 9,241 meters (30,318 feet) set at Garden City, New York, 30 July 1918.²
Rohlfs took off at 12:06 p.m. and reached his peak altitude 1 hour, 15 minutes later. The air temperature was -43 °F. (-41.7 °C.). He touched down after 1 hour, 53 minutes.
The Curtiss 18T Wasp was a two-place single-engine triplane fighter designed and built for the United States Navy at the end of World War I. A3325 had been loaned to the U.S. Army to set an airspeed record of 163 miles per hour (262 kilometers per hour), before being returned to Curtiss for additional testing. It was fitted with a set of longer wings and redesignated 18T-2. The second 18T, A3326, retained the standard 32’–½” (9.766 meters) wings and was redesignated 18T-1.
The Curtiss 18T-2 was 23 feet (7.010 meters) long with a wingspan of 40 feet, 7½ inches (12.383 meters). It weighed 1,900 pounds (862 kilograms). The airplane was powered by a water-cooled, normally-aspirated, 1,145.11-cubic-inch-displacement (18.765 liter) Curtiss-Kirkham K-12 60° single-overhead-cam V-12 engine which produced 375 horsepower at 2,250 r.p.m., and 400 horsepower at 2,500 r.p.m. The K-12 drove a two-bladed fixed-pitch propeller through a 0.6:1 gear reduction.
A3325 later crashed during a test flight. Its sistership, A3326, suffered a crankshaft failure and was destroyed. The Curtiss 18T was never placed in series production.
1 August 1911: After 33 flight lessons over a four-month period at the Moisant Aviation School at Hempstead, Long Island, New York, Harriet Quimby took her flight test and became the first woman to receive a pilot’s license, Number 37, from the Aero Club of America. She was “America’s First Lady of the Air.”
She was well-known throughout the United States and Europe, and wore a purple satin flying suit.
On 16 April 1912 she became only the second pilot to fly across the English Channel when she flew from Dover to Calais in 59 minutes with a Blériot monoplane.
Eleven months after receiving her pilot’s license, 1 July 1912, Harriet Quimby was killed when she fell from her Blériot XI during a flying demonstration at Squantum, Massachusetts.
12 June 1918: 2nd Lieutenant James Harold Doolittle, Aviation Section, Signal Officers’ Reserve Corps, was granted Aero Club of America pilot certificate No. 1702 on behalf of the Fédération Aéronautique Internationale.
The license was signed by Alan Ramsay Hawley, President, and William Hawley, Secretary.
8 June 1911: The Aero Club of America, as representative of the Fédération Aéronautique Internationale, issued Aviator Certificate Number 1 to Glenn Hammond Curtiss. The document was signed by Allan A. Ryan, president of the club, and G. F. Campbell-Wood, secretary.
23 April 1915: Lieutenant Patrick Neison Lynch Bellinger, United States Navy, flew a Burgess-Dunne hydroaeroplane to an altitude of 10,000 feet (3,048 meters) over Pensacola Bay, Florida.
The Aero Club of America certified Lieutenant Bellinger’s record:
Homolgation of the altitude record made by Lieut. P. N. L. Bellinger at Pensacola Bay, Fla., on April 23rd last has been officially recognized and awarded as follows: American altitude record, aviator alone, hydroaeroplane, 10,000 feet. This height was reached in one hour, nineteen minutes. It is interesting to note the climbing record in connection with this flight, 6,000 feet being attained in 24 minutes and 8,000 feet in 41 minutes.

The Burgess-Dunne Model BD-5, U.S. Navy serial number AH-10, was a licensed variant of the British Short Brothers-built Dunne D.5. The configuration was designed by Lieutenant John William Dunne, F.R.Ae.S., and was based on his observations of the Roemer’s Alsomitra macrocarpa seeds, although his design essentially reversed the aerodynamic features of the seed.
According to Wikipedia:
The seed or samara of this species is unusual in having two flat bracts extending either side of the seed to form a wing-like shape with the seed embedded along one long edge and the wings angled slightly back from it. As the seed ripens the wings dry and the long edge furthest from the seed curls slightly upwards. When ripe, the seed drops off and its aerodynamic form allows it to glide away from the tree. The wing spans some 13 cm and can glide for great distances. The seed moves through the air like a butterfly in flight — it gains height, stalls, dips and accelerates, once again producing lift, a process termed phugoid oscillation. In the past it was often found on the decks of ships at sea.
The seed’s relative stability in pitch and roll inspired Igo Etrich, a pioneer of early aviation. The contemporary pioneer J.W. Dunne also studied the seed but discarded it as inspiration because it was not directionally stable.
The BD-5 was a two-place, single-engine, four-bay biplane with a single pontoon and wingtip-mounted floats. The wings were swept 30° and the lower wing was staggered significantly behind the upper. Both wings had anhedral, and the upper wing had slightly more area and a negative twist. There was no tail, rudder or elevators. The ailerons also acted as elevators. The design was very stable and it could not be forced into a stall.
The Burgess-Dunne was 24 feet, 8 inches (7.518 meters) long, with a wingspan of 46 feet, 0 inches (14.021 meters). The wings have a chord of 6 feet, 0 inches (1.829 meters) vertical gap between the wings was 6 feet, 0 inches (1.829 meters). The total wing area is 545 square feet (50.63 square meters). The airplane’s empty weight was 1,450 pounds (658 kilograms), and it had a gross weight of 1,700 pounds (771 kilograms).
The pontoon had a single hydrodynamic step. It was 17 feet, 8 inches (5.385 meters) long, 3 feet, 1 inch (0.940 meters) wide and had a maximum depth of 1 foot, 2 inches (0.356 meters).
The airplane was powered by a water-cooled, normally-aspirated 567.450-cubic-inch-displacement (9.299 liter) Curtiss OXX-2 overhead valve 90° V-8 engine with dual ignition. It had two valves per cylinder, a compression ratio of 4.92:1, and produced 100 horsepower at 1,400 r.p.m. The OXX-2 was a direct-drive engine and turned a two-bladed, 8 foot (2.4 meter) diameter propeller in a pusher configuration.
The Burgess-Dunne had a fuel capacity of 22 Imperial gallons (100 liters) and carried 4 gallons (18 liters) of lubricating oil.
During flight testing, the Burgess-Dunne Hydroaeroplane averaged 58.75 miles per hour (94.55 kilometers per hour) ground speed over a triangular course with a 10 knot wind (11.5 miles per hour, or 5.4 meters per second).
One Burgess-Dunne had been ordered by the Navy on 5 December 1914. The cost was $5,000.00, less engine. It was delivered in April, 1915. After being flown to the altitude record, AH-10 was used for artillery spotting at Fort Monroe, Virginia. It was the first U.S. Navy aircraft to be armed with a machine gun, a .30-caliber Benét-Mercié machine rifle, and bomb racks.
On 7 March 1916, AH-10 was damaged in a collision with a sailing vessel off Mobile, Alabama. The pilot, Lieutenant Edward Orrick McDonnell, U.S. Navy, was not hurt. After repair, the airplane was returned to service. (Lieutenant McDonnell had been awarded the Medal of Honor for his actions at the Battle of Veracruz, 21–22 April 1914. He rose to the rank of Vice Admiral.)
Patrick Neison Lynch Bellinger was born 8 October 1885 at Cheraw, South Carolina. He was the son of Carnot Ambrose Bellinger and Eleanor Lynch Bellinger.
A 1907 graduate of the U.S. Naval Academy, Annapolis, Maryland, he served at sea aboard the battleship USS South Carolina (BB-26) before being assigned as commanding officer of the C-class submarine, C-4 (SS-15). He was then trained as an airplane pilot. Lieutenant Bellinger was Naval Air Pilot No. 4.
During the Veracruz campaign, 1914, Lieutenant Bellinger flew reconnaissance over enemy lines. It was here that a United States military airplane first came under enemy fire. He was nominated for the Medal of Honor for his actions there.
In 1919 he was awarded the Navy Cross, “For distinguished service in the line of his profession as commanding officer of the seaplane NC-1 which made a long overseas flight from Newfoundland to the vicinity of the Azores in May 1919.”
Lieutenant Commander Bellinger married Elsie McKeown of Pennsylvania, 24 July 1915. She died at Washington, D.C., 9 February 1920. He married his second wife, Miriam Georgia Benoist, 14 April 1921.
Bellinger progressively rose in rank and responsibility. As rear admiral, he commanded Patrol Wing 2 at Pearl Harbor at the time of the surprise attack by the Imperial Japanese Navy. During World War II, he was promoted to the rank of Vice Admiral and served as Commander Air Force, Atlantic Fleet. Vice Admiral Bellinger retired from the Navy in 1947.
Vice Admiral Patrick Neison Lynch Bellinger, United States Navy (Retired), died 29 May 1962 at the Chesapeake & Ohio Hospital, Clifton Forge, Virginia. He is buried at the Arlington National Cemetery.
