| Ballooning, using gas balloons (which require no power, fuel or motors), was on the Summer Olympic Games programme in 1900. The aeronautical pioneer Henry de La Vaulx set two world records for distance and duration piloting a balloon flight. These ballooning events have generally not been classified as official. All events at the 1900 Games that satisfied all four of these retrospective selection criteria — restricted to amateurs, open to all nations, open to all competitors and without handicapping — are now regarded as Olympic events, except for those in one sport — ballooning. |
