Here's a short story:

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. 

On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot-air-balloon flight, reaching . He launched from downtown Bombay, India, and landed south in Panchale. The previous record of had been set by Per Lindstrand on June 6, 1988 in Plano, Texas. (End of story)
