The co-pilot who survived the Tenerife aircraft disaster

In March 1977, two jumbo jets collided at Tenerife Airport killing 583 people. It was the worst crash in aviation history.

The two Boeing 747s were among those diverted from nearby Gran Canaria Airport earlier in the day due to security concerns.

But when the all clear came to resume their journeys, a combination of bad weather and miscommunication meant that Pan Am Flight 1736 was still on the runway as KLM Flight 4805 attempted take-off.

Captain Robert Bragg was the co-pilot aboard the Pan Am plane, and was one of the few who survived the collision. He spoke to Witness about that terrible disaster.
