On July 3, 1968, an Airspeed Ambassador propeller aircraft carrying eight racehorses slammed into two parked jets at London's Heathrow Airport and cartwheeled into Terminal 1, which was then under construction.
Six of eight people aboard the aircraft were killed. The racehorses also died.
Another 31 people on the ground were injured.
The accident was blamed on a mechanical problem. The aircraft was operated by BKS Air Transport. It had been recently converted to carry horses.
