The car literally took off (and landed) like an airplane.
A lot can go wrong in 24 hours of racing, and Le Mans has a long history of cars not making it until dawn. Perhaps one of the craziest and most uncanny of such crashes was Peter Dumbreck's 1999 accident where his Mercedes CLR-GT1 got caught in another cars slipstream, causing Dumbreck's car to take flight, tumble end-over-end mid air and land in the trees. Many hard core fans probably remember the moment first hand, but in case you missed it, the video recently popped up on YouTube.
Amazingly, not only was Dumbreck not killed, he actually walked away unscathed.
