German Olympian Stephan Feck exited the London Aquatics Centre pool red-faced and red-backed after a mistimed second dive that left onlookers shocked.
Attempting a forward, three and a half somersault pike in the qualifying round of the men's three-metre springboard, the 22-year-old's execution was far from perfect.
Feck slipped off the board and lost control of his let left leg, causing him to make make one too many rotations and enter the pool flat on his back.
The loud and painful splash was one rarely heard.
The sport normally delivers immaculate dives as athletes endeavour to produce as little splash as possible on entry.
After lifting himself out of the pool, Feck was consoled by German teammate Patrick Hausding as his score of zero was announced over the PA system. That's right, zero. Not one judge awarded him any points.
Though three metres does not seem very far to bomb a dive from, the physically demanding sport does take its toll on the daredevils who participate.
