Accidents & Serious Incidents involving B703

  • B703, Sydney Australia, 1969 (BS RE) (On 1 December 1969, a Boeing 707-320 being operated by Pan Am and making a daylight take off from Sydney, Australia ran into a flock of gulls just after V1 and prior to rotation and after a compressor stall and observed partial loss of thrust on engine 2 (only), the aircraft commander elected to reject the take off. Despite rapid action to initiate maximum braking and the achievement of full reverse thrust on all engines including No 2, this resulted in an overrun of the end of the runway by 170m and substantial aircraft damage. A full emergency evacuation was carried out with no injuries to any of the occupants. There was no fire.)
