Mission Impossible 2 - Bike with Anti-Grav Generator
When Ethan jumps his bike up on the wooden bridge, in the chase scene, his bike jumps in a straight line, not an arc, as common physics would have it. Play it a few times and you will see. You won´t see it in slow motion, though.
It's pretty obvious he rode the Bike down a ramp, that was later edited out with Digital masterey... Much like the harnesses, and ropes/cables on the climbing, and on Nya's scene hanging from the Audi.
That is why the bike appears to ride flat off the hill, and onto the bridge
