Pope Knocked Down at Mass [YOUTUBE VIDEO]

Pope Benedict was unfortunately knocked down by a woman before the Christmas Eve mass -- he was unhurt, and completed the ceremony. Of course, we can rely on user-generated content to capture such remarkable events. In this case a bystander with a cellphone caught the moment on film while the TV cameras were pointed elsewhere.

It's only the latest in a string of events -- from the Hudson plane crash early this year, to the passing of Neda in Iran -- where people on the ground captured shocking moments the media would otherwise have missed.
