Highest altitude reached by a hovercraft

The highest altitude reached by a hovercraft was  4,983 m (16,050 ft) reached by Neste Enterprise and her crew of ten at the navigable source of China's Yangtze River on 11 June 1990. Operating hovercraft at such altitudes is problematic both because of the challenging terrain and the thin air, which makes hovering more difficult.

The greatest altitude at which a hovercraft is operating is on Lake Titicaca, Peru, where since 1975 an HM2 Hoverferry has been hovering 3,811 m (12,506 ft) above sea level.
