mmm i have to agree its a little bit of media looking for somthing to do really, i cant even say the reinactment represents the jump.
From what i remember Bud edkins, Mc queen and another riding buddy went out and practiced that jump a days before the location was used and they all cleared some string they had set up to represent the height, they took a spade and made a ramp behind the mound as a launchpad, they said they then covered it up to make it look less intense for the studio boffins and mc queen was going to do it, but when they came to set up for the shot the studio put there foot down and said No ( as they did to a few scenes in the bullit) and in the end Bud did it, most Studio crew where surprised he did it in one take, reality was they all had cleared it days before and had well rehearsed the run up and speeds needed.
Although i still think it would be a sore arse landing as i kid i always thought the bike changed from the one in the shot before to the one in the air even to the point it had knobblies on it, anyhow that aside for that era a jump that high was failry standard for these guys, on the TT curcuit you would see track guys clearing that height on lesser run ups. If i look through my Photo album a few images show that, like :
Pic 1 is Ricky Graham and Alex jorgensen with Air at Cow palace, TT, ( Boss frame 650 YAm and triumph) jump take off is about 4ft so same height as Buds
Pic 2 is Ricky Graham and hank scott ( Boss frame triumph/yamaha) Flat jump
I guess what im saying is i agree with the comments above its an Iconic moment in Movies, not a overwelming jump though, and the Papers re-inactment really was a waste of time...........
But thanks for the post, it show Vmx is coming mainstream
