Hi,
not the shortest runway ever but pretty impressive (and frightening):
Heinz-Dieter Kallbach landed an IL 62 on a 860m gras strip. The ex-Interflug plane was still in one piece after this...
Kind regards,
Peter
PS: HD Kallbach was the Germania pilot who was beaten up for minutes together with his FO after a lunatic entered his front office in 2000 and tried to kill them with the fire axe...
