I've done 2 or 3 fairly high jumps. The first was at Smokey Mountain, coming up the front straight at the jump where you go off-tarmac to the right. Driving a 500-hp S4, I failed to brake for the transition and stood it on its butt, at least a carlength in the air, travelled that way down to the invisible air wall over the barrier at the following right, where it slammed to the ground and did a 360.
The second was driving a Stage 4 GT One road car at the Like The Wind race. I was bored and attempting to do a lap by looking backwards all the way around and steering reversed when I got crossed up and hooked right, up into the rail at the top of the banking. The car again stood on its tail (with me looking at the ground this time) and went up to hit the air ceiling, the crashed back down and did a pirouette on the guard rail before slapping back down to the track. I still won by a mile.
Last big one was in a 700-hp Vanquish at Laguna. Missing the brake point at the corkscrew by a fraction of a second meant big air into the tire wall, which I did a few times. The best one, though, I was too far to the right, and also put the right wheels up onto the curb. That made for a great "A-team/F&F" trick with the car flying knifeedge through the air on its left side before slamming into the air wall at the tires.
At one Amateur race at Trial Mountain, the AI Focus rally car tried for an inside pass at the "Freejack" chicane and ended up flying across the hood of my car, nose down, so I could see the whole underside of it. He made the pass but slammed into the left wall on the landing so I got back around him for the win.
