You need to make it to the ground, but your pesky enemies want to stop you. Rip them from their planes (No relation to United) and fight back! Shoot them, kamikaze into them, or throw your plane at a enemy by hoping out!
Watch out for enemy planes and shrapnel, luckily you can only take damage when you are outside of a Plane. So tear your enemies from their seats and give them hell!
