Algodoo

The plane flys with air friction and the car is wheel driven with some air friction assistance.
Follow the green arrows, use the car mode for the ground level obstacles and transform to a plane for the airborne obstacles. The obstacles can damage the car/plane if you hit them.
There is even a short police chase in this game, but you can loose him at the river crossing.
