Oh, I just watched the Hong Kong clips, haha really amazing me, haha.
We had many cameras there to shot this, (four cameras on the car, one camera underleaf the jumping stage, one one power-pod (me), another three cameras around the field, and the main following camera) of course it is a one shot deal, I also don't think that Danny and Oswald want to try a second take.
I saw them were very worry before the roll-over. They considered for a long time before they get on the stunt car. @_@
Thanks Amazing Race!
