Anyone got any ideas on how to get this achievement?

well my mate got it in demolition derby he was going over a jump the back end hit the top of a car and his car just sailed before it nose dived into the barrier i guess its just luck really

yeah I have heard people talk about doing it that way but I cant seem to. I thought maybe the race track san francisco gran pirx circuit i think I thought aybe you could catch air off one of them but not sure what car to use ad most just wanna stick to the ground.

well i think you can do it on the track where you have to race the lacetti's in grid world if you hit eiter of the tires at the start it flips you but dont know if it will get you up long enough

Wow, this was a hard achievement to get for some. Im not bragging, but I got incredibly lucky then. I was playing my second race, the one in the Chevy after you do the Viper first race, and I crashed and got 2 achievements: the car wrecked one, and airborne. I had no idea that this was supposed to be hard to get.

Ok this isnt to get a achivement but on Le Mans track one with no corners on the straight and get the Audi R10 and go full boar down the straight but brake at the end keep goin and jump of the end things and smash your car
