• 1934-01-30: 21.946 km (72,000 ft); USSR balloon Osoaviakhim-1. The three crew were killed when the balloon broke up during the descent.
• 1935-11-10: 22.066 km (72,400 ft); Captain O. A. Anderson and Captain A. W. Stevens (U.S. Army Air Corps) ascended in the Explorer II gondola from the Stratobowl, near Rapid City, South Dakota, for a flight that lasted 8 hours 13 minutes and covered 362 kilometres (225 mi).
• 1956-11-08: 23.165 km (76,000 ft); Malcolm D. Ross and M. L. Lewis (U.S. Navy) in Office of Naval Research Strato-Lab I, using a pressurized gondola and plastic balloon launching near Rapid City, South Dakota, and landing 282 km (175 mi) away near Kennedy, Nebraska.
• 1957-06-02: 29.4997 km (96,784 ft); Captain Joseph W. Kittinger (U.S. Air Force) ascended in the Project Manhigh 1 gondola to a record-breaking altitude.
• 1957-08-19: 31.212 km (102,400 ft); above sea level, Major David Simons (U.S. Air Force) ascended from the Portsmouth Mine near Crosby, Minnesota, in the Manhigh 2 gondola for a 32-hour record-breaking flight. Simons landed at 5:32 p.m. on August 20 in northeastern South Dakota.
• 1960-08-16: 31.333 km (102,800 ft); Testing a high-altitude parachute system, Joseph Kittinger of the U.S. Air Force parachuted from the Excelsior III balloon over New Mexico at 102,800 ft (31,300 m). He set world records for: high-altitude jump; freefall diving by falling 26 km (16 mi) before opening his parachute; and fastest speed achieved by a human without motorized assistance, 988 km/h (614 mph).^[3]
• 1961-05-04: 34.668 km (113,740 ft); Commander Malcolm D. Ross and Lieutenant Commander Victor A. Prather, Jr., of the U.S. Navy ascended in the Strato-Lab V, in an unpressurized gondola. After descending, the gondola containing the two balloonists landed in the Gulf of Mexico. Prather slipped off the rescue helicopter's hook into the gulf and drowned.^[a]
• 1966-02-02: 37.6 km (123,000 ft); Amateur parachutist Nicholas Piantanida of the United States with his "Project Strato-Jump" II balloon. Because he was unable to disconnect his oxygen line from the gondola's main feed, the ground crew had to remotely detach the balloon from the gondola. His planned free fall and parachute jump was abandoned, and he returned to the ground in the gondola. Nick was unable to accomplish his desired free fall record, however his spectacular flight set other records that held up for 46 years. Because of the design of his glove, he was unable to reattach his safety seat belt harness. He endured very high g-forces, but survived the descent. Piantanida's ascent is not recognized by the Fédération Aéronautique Internationale as a balloon altitude world record, because he did not return with his balloon, although that was not the feat he was trying to accomplish. On this second attempt of "Project Strato-Jump", Nick Piantanida took with him 250 postmarked air-mail envelopes and letters. At the time, these letters were the first covers to have ever been delivered by the U.S. Post Office via space. The habit of taking cover letters to space continued with the Apollo Program; in 1972 there was a scandal involving the Apollo 15 astronauts. It is unclear if any of the "Project Strato-Jump" covers survived, and were eventually mailed to the intended recipients.
• 2012-10-14: 38.969 km (127,850 ft); Felix Baumgartner in the Red Bull Stratos balloon. The flight started near Roswell, New Mexico, and returned to earth via a record-setting parachute jump.
• 2014-10-24: 41.424 kilometres (135,910 ft); Alan Eustace, a senior vice president at the Google corporation, in a helium balloon, returning to earth via parachute jump during the StratEx mission executed by Paragon Space Development Corporation.^[5][6]

5th november 1966 polish pilot Stanisław Józefczak with passenger Jan Tarczoń on polish woodmade training glider SZD-9 Bocian climb to 12560m over Tatry mountain in Poland On February 17, 1986, the highest altitude obtained by a soaring aircraft was set at 14.938 km (49,009 ft) by Robert Harris using lee waves over California City, United States.^[11] The flight was accomplished using the Grob 102 Standard Astir III.^[12]

This was surpassed at 15,460 m (50,720 ft) set on August 30, 2006, by Steve Fossett (pilot) and Einar Enevoldson (co-pilot) in their high performance research glider Perlan 1, a modified Glaser-Dirks DG-500.^[11] This record was achieved over El Calafate (Patagonia, Argentina) and set as part of the Perlan Project.^[13]

This was raised at 15.902 km (52,172 ft) on September 3, 2017^[14] by Jim Payne (pilot) and Morgan Sandercock (co-pilot) in the Perlan 2,^[15] a special built high altitude research glider. This record was again achieved over El Calafate and as part of the Perlan Project.^[13]

On September 2, 2018, within the Airbus Perlan Mission II, again from El Calafate, the Perlan II piloted by Jim Payne and Tim Gardner reached 23.203 km (76,124 ft), surpassing the 22.475 km (73,737 ft) attained by Jerry Hoyt on April 17, 1989, in a Lockheed U-2: the highest subsonic flight.^[16]

Early, disputed attempts to fly or glide near the ground

Public, documented flights

On June 21, 1972, Jean Boulet of France piloted an Aérospatiale SA 315B Lama helicopter to an absolute altitude record of 12,440 metres (40,814 ft).^[69] At that extreme altitude, the engine flamed out and Boulet had to land the helicopter by breaking another record: the longest successful autorotation in history.^[70] The helicopter was stripped of all unnecessary equipment prior to the flight to minimize weight, and the pilot breathed supplemental oxygen.

The highest altitude obtained by a paper plane was previously held by the Paper Aircraft Released Into Space (PARIS) project, which was released at an altitude of 27.307 kilometres (89,590 ft), from a helium balloon that was launched approximately 160 kilometres (99 mi) west of Madrid, Spain on October 28, 2010, and recorded by The Register's "special projects bureau". The project achieved a Guinness world record recognition.^[71][72]

This record was broken on 24 June 2015 in Cambridgeshire, UK by the Space Club of Kesgrave High School, Suffolk, as part of their Stratos III project. The paper plane was launched from a balloon at 35.043 kilometres (114,970 ft).^[73][74]

The current world-record for highest cannon projectile flight is held by Project HARP’s 410 mm (16 in) space gun prototype, which fired a 180 kg (400 lb) Martlet 2 projectile to a record height of 180 kilometres (590,000 ft; 110 mi) in Yuma, Arizona, on November 18, 1966. The projectile’s trajectory sent it beyond the Kármán line at 100 km (62 mi), making it the first cannon-fired projectile to do so.^[75]

The Paris Gun (German: Paris-Geschütz) was a German long-range siege gun used to bombard Paris during World War I. It was in service from March–August 1918. Its 106-kilogram (234 lb) shells had a range of about 130 km (80 mi) with a maximum altitude of about 42.3 km (26.3 mi).
