Ground Vehicle Respawn

It would be interesting if instead of having the ground vehicles respawn on the ground they were air dropped from a plane. The respawn time would be replaced with the time it takes for the plane to fly over, drop the vehicle(s), and for the vehicles to float down to the ground via parachute. It would be more realistic than vehicles magically appearing, players could visually see the vehicles arriving, and there may even be an opportunity to take out the delivery plane and/or air dropped vehicles in the air plus it would add some more obstacles in the air for planes and helicopters to worry about.
