I was interested in what happened to him and noticed you can turn on comments on that page. Most of them are pretty lame, but some of the interesting ones are:
- it was more than 600lb
- it was Steve Wong benching 823lb
- sound was from the cameras, not his ribs or thumbs breaking
- it was Steve Wong, 832lb, 2nd attempt, no injuries, got it on his 3rd attempt
- the guy is Gene Rychlak
- it might have come down that fast because his bench shirt tore
So, a bit inconclusive really.
