This accident can easily be named the most famous racing crash in history, partly due to the way it happened, and largely thanks to Ron Howard's movie "The Rush" starring Chris Hemsworth. Trying to make up time after an unplanned pit-stop on the first lap, Austrian Niki Lauda attacked a curb in the turn “Bergwerk” way to aggressively. As a result of his haste his Ferrari 312 T2 flew off the track promptly hitting the fence and catching fire. Lauda suffered severe burns, however, despite this fact, he went on and participated in the Italian Grand Prix only six weeks after the accident.
