Chinook - The special forces flight in war and peace

David McMullon has spent 2000 hours flying Chinook helicopters and it's no easy task - 100ft long with a blade that's over 3ft wide, it takes a team of four to fly and has the potential to carry 120 men. Even after rigorous training, accidents happen.

David McMullon has lost 15 of his friends in helicopter crashes - a mistake below one hundred feet can turn a Chinook from a flying machine into a falling rock in the blink of an eye. McMullon's experiences include actual war time encounters with SAM missiles in the Gulf War and in Northern Ireland.

And it was McMullon's task to fly up to Scotland on December 21 1988. What he and his team found was the harrowing debris of a passenger jet over Lockerbie and chaos on the ground.
