Disintegration-yikes!

This is NOT supposed to happen when you crash. John was going 5 mph in a school zone when a car slammed on their brakes for a pedestrian. He ran into the back of the car and his bike crumbled. Please note, his wheels are still true, tires not flat, fork not cracked. Frame: disintegrated. We think he's lucky he wasn't going 55 down Potisi or the back side of the loop (Vegas rides) and hit a bump, what would have happened then? Anyone have a nice road frame for a 6'4" Tom Boonen type rider?
