A helicopter can be jump-started by a car.
James McIntosh, a ski centre owner, has revealed in 1974 the Bell 47G-5 chopper he had parked, in Bellabeg in the Highlands in Scotland, near a garage was blocking the road so he borrowed his father's Rover to get it back up and running after the pistons failed, and within 10 minutes it was up in the air.
He told the Daily Record: ''We wheeled the chopper out onto the road and went to fire up the engine and there was nothing.
''It was a piston driven engine which can sometimes be difficult to start, especially after being hosed down and cleaned.
''Knowing that the local bus and other folks would be needing past soon we had to act quickly.
''As the battery on the helicopter is fairly small a car can jump start it, so I hijacked my father Gibbie's Rover.
The road was at a standstill for about 10 minutes while we got the helicopter off the ground.
''There were a few bemused drivers and some of the locals were peering out their doors to watch proceedings.
''It's not every day a helicopter uses the main road through Strathdon as a helipad.''
