The highest bird strike reported to date occurred on November 29, 1973, at 37 000 feet. It involved the collision of a commercial jet airliner and a Ruppeli's Griffon Vulture which was flying over Abijan, Ivory Coast. Another reported bird strike occurred at 33 000 feet involving a goose and a Pan Am Boeing 747.
