This past spring, British TV show Fifth Gear aired stuntman Steve Truglia performing a Hot Wheels inspired feat. The daredevil completed the world's largest 360° loop-the-loop. Death was a definite risk.
Says Daily Mail,
"...John Nolan, producer of Fifth Gear, admitted that Mr. Truglia was dicing with death by taking on the challenge - known to stuntmen as the 'death loop'. 'This is definitely the highest loop-the-loop in a real car ever,' he said. 'If he had blacked out he might not be here now.'
If Mr. Truglia had been too timid in his acceleration, his yellow Toyota would have reached the top of the track and dropped like a stone. But if he had driven in too fast, the G-force generated could have knocked him unconscious. Either way, his route down from the high point of the 40ft loop would have been, shall we say, less than graceful.
But Mr Truglia's timing and speed were perfect."
Watch for yourself.
