Just watch the guy in green getting out of the car and what his first reaction is.

Wim Van Est, 1951 Tdf Stage 12. First Dutchman to gain yellow, the day before. Next day, in the descent of the Col d'Aubisque:

This is in the a-la-Frank category, or maybe more Horrillo without the tragic consequences: 70m down a ravine without serious injuries. Climbed back to the road and wanted to carry on. Was persuaded to get a hospital check-up instead, pronto. Certainly not one of the worst crashes ever, but one I have read about so often, and seen many photos of the drop. Never even knew there was actual footage. Just found it, so thought this might be a good place to share. There is a plaque on that spot now.
