Australian Channel 9 cameraman Joe Previtera was recording a dramatic sweep of the pitch at the Melbourne Cricket Ground, when he did the impossible -- fell off his Segway.
The supposedly un-fall-off-able electric personal scooter thing didn't suffer a tech failure, it was simple human error -- Joe didn't spot a helmet sitting on the ground. He hit it, sending the Segway's gyros haywire, and was thrown off. Australian wicketkeeper Brad Haddin picked him up, but it was too late to save Joe's accident being broadcast, live, to viewers around the world. [YouTube via Giz.au]
