Id be scared to hit a bird because there is a chance you looe the plane what would a one pount object mmoving at 70 mph do to a win idk but i bet it wouldnt be prettty like if you loose half a wing your game over ( i know bill hample brought on down but there aint many guys good enough to do that and evan then her got luckey that it fell inot a knife edge if it would have fallen into a flat spin it owuld have been game over )
