Flight altitude record. This listing of flight altitude records are the records set for the highest aeronautical flights conducted in the atmosphere, set since the age of ballooning.

Some, but not all of the records were certified by the non-profit international aviation organization, the Fédération Aéronautique Internationale (FAI). One reason for a lack of 'official' certification was that the flight occurred prior to the creation of the FAI.

For clarity, the "Fixed-wing aircraft" table is sorted by FAI-designated categories as determined by whether the record-creating aircraft left the ground by its own power (category "Altitude"), or whether it was first carried aloft by a carrier-aircraft prior to its record setting event (category "Altitude gain", or formally "Altitude Gain, Aeroplane Launched from a Carrier Aircraft"). Other sub-categories describe the airframe, and more importantly, the powerplant type (since rocket-powered aircraft can have greater altitude abilities than those with air-breathing engines).

An essential requirement for the creation of an "official" altitude record is the employment of FAI-certified observers present during the record-setting flight. Thus several records noted are unofficial due to the lack of such observers.

 1960-08-16:  ; Testing a high-altitude parachute system, Joseph Kittinger of the U.S. Air Force parachuted from the Excelsior III balloon over New Mexico at . He set world records for: high-altitude jump; freefall diving by falling  before opening his parachute; and fastest speed achieved by a human without motorized assistance, .
 1961-05-04: ; 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.
 1966-02-02: ; 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: ; 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: ; 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.

Hot-air balloons

Uncrewed gas balloon 
During 1893 French scientist Jules Richard constructed sounding balloons. These uncrewed balloons, carrying light, but very precise instruments, approached an altitude of .

A Winzen balloon launched from Chico, California, in 1972 set the uncrewed altitude record of . Its volume was .

On September 20, 2013, JAXA launched an ultrathin film balloon called BS13-08 made of 2.8 μm thick polyethylene film with a volume of , which was  in diameter. The balloon rose at a speed of  and reached an altitude of , surpassing the previous world record set in 2002

This was the greatest height a flying object reached without using rockets or a launch with a cannon.

Gliders 

On February 17, 1986, The highest altitude obtained by a soaring aircraft was set at  by Robert Harris using lee waves over California City, United States.  The flight was accomplished using the Grob 102 Standard Astir III.

This was surpassed at  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. This record was achieved over El Calafate (Patagonia, Argentina) and set as part of the Perlan Project.

This was raised at  on September 3, 2017 by Jim Payne (pilot) and Morgan Sandercock (co-pilot) in the Perlan 2, a special built high altitude research glider. This record was again achieved over El Calafate and as part of the Perlan Project.

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 , surpassing the  attained by Jerry Hoyt on April 17, 1989, in a Lockheed U-2: the highest subsonic flight.

Fixed-wing aircraft

Piston-driven propeller aeroplane 
The highest altitude obtained by a piston-driven propeller UAV (without payload) is . It was obtained during 1988–1989 by the Boeing Condor UAV.

The highest altitude obtained in a piston-driven propeller biplane (without a payload) was  on October 22, 1938, by Mario Pezzi at Montecelio, Italy in a Caproni Ca.161 driven by a Piaggio XI R.C. engine.

The highest altitude obtained in a piston-driven propeller monoplane (without a payload) was  on August 4, 1995, by the Grob Strato 2C driven by two Teledyne Continental TSIO-550 engines.

Jet aircraft 
The highest current world absolute general aviation altitude record for air breathing jet-propelled aircraft is  set by Aleksandr Vasilyevich Fedotov in a Mikoyan-Gurevich E-266M (MiG-25M) on August 31, 1977.

Rocket plane 
The record for highest altitude obtained by a crewed rocket-powered aircraft is the US Space Shuttle (STS) which regularly reached altitudes of more than  on servicing missions to the Hubble Space Telescope.

The highest altitude obtained by a crewed aeroplane (launched from another aircraft) is  by Brian Binnie in the Scaled Composites SpaceShipOne (powered by a Scaled Composite SD-010 engine with  of thrust) on October 4, 2004, at Mojave, California. The SpaceShipOne was launched at over .

The previous (unofficial) record was  set by Joseph A. Walker in a North American X-15 in mission X-15 Flight 91 on August 22, 1963. Walker had reached 106 km – crossing the Kármán line the first time – with X-15 Flight 90 the previous month.

During the X-15 program, 8 pilots flew a combined 13 flights which met the Air Force spaceflight criterion by exceeding the altitude of , qualifying these pilots as being astronauts; of those 13 flights, two (flown by the same civilian pilot) met the FAI definition of outer space: .

Mixed power
The official record for a mixed power aircraft was achieved on May 2, 1958, by Roger Carpentier when he reached  over Istres, France in a Sud-Ouest Trident II mixed power (turbojet & rocket engine) aircraft.

The unofficial altitude record for mixed-power-aircraft with self-powered takeoff was  on December 6, 1963, by Major Robert W. Smith in a Lockheed NF-104A mixed power (turbojet and rocket engine) aircraft.

Electrically powered aircraft 
The highest altitude obtained by an electrically powered aircraft is  on August 14, 2001, by the NASA Helios, and is the highest altitude in horizontal flight by a winged aircraft. This is also the altitude record for propeller driven aircraft, FAI class U (Experimental / New Technologies), and FAI class U-1.d (Remotely controlled UAV, weight ).

Rotorcraft 
On June 21, 1972, Jean Boulet of France piloted an Aérospatiale SA 315B Lama helicopter to an absolute altitude record of . 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. The helicopter was stripped of all unnecessary equipment prior to the flight to minimize weight, and the pilot breathed supplemental oxygen.

Paper airplanes 
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 , from a helium balloon that was launched approximately  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.

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 .

Cannon rounds 
The current world-record for highest cannon projectile flight is held by Project HARP’s  space gun prototype, which fired a  Martlet 2 projectile to a record height of  in Yuma, Arizona, on November 18, 1966. The projectile’s trajectory sent it beyond the  Kármán line at , making it the first cannon-fired projectile to do so.

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  shells had a range of about  with a maximum altitude of about .
