A "violent argument" in the cockpit may have led to Britain's deadliest air accident of all time.
All 118 people on board were killed when British European Airways Flight 548 from London Heathrow to Brussels crashed in a field in Staines, Surrey on June 18, 1972.
Over an hour before the plane was due to depart, a heated row broke out between the pilot, Stanley Key, and a colleague named Flavell, according to the Daily Star.
