Was an RAF plane responsible for the crash of a Norwegian civilian plane at the height of the Cold War? Paul Henley investigates the truth behind the so-called Mehamn crash.

At the height of the Cold War, a passenger plane crashed in Northern Norway, killing all on board – thirteen passengers and two crew.

Air accident Investigators concluded the accident was the result of a convergence of freak events but there are many who remain sceptical and who believe another aircraft may have been involved.

On the day in question, British fighter planes were participating in NATO military exercise in the region. Northern Norway borders the former Soviet Union – it was the dividing line of the Cold War.

Norwegian Aircrash Investigators and the British military have always denied that military aircraft were in the crash area, a no fly zone right next to the Russian border.

But the mystery surrounding the crash persists, with dozens of witnesses claiming to have seen British Harriers in the area. This has led to the establishment of a third inquiry in Norway into the events of that day, due to report in the summer of this year.

Paul talks to military and civilian witnesses. He meets bereaved family members. He questions Norwegian investigators, and puts questions to the British MOD. He unravels the tragedy of the plane crash and questions whether the truth surrounding the Mehamn accident remains the victim of the Cold War.
