In case you missed it, a weatherman in Australia named Grant Denyer did a segment from the passenger seat of a STUNT PLANE Tuesday morning.  And in the middle of it, the G-forces got to him and made him PASS OUT on live TV.

He was only unconscious for a few seconds, but you can check out the video online.  According to the pilot, they were experiencing about 8 G's when it happened . . . meaning 8 times the force of gravity.
