What are some glitches for warhawk

There is an awesome glitch at fortress... All you have to do is get in a plane and go to any corner of fortress and press triangle and spin your plane around and you will go through the ground and when you get through the ground, stop your plane quickly before you hit the water because you go through the water and DIE!!!! You can also shoot people through the ground!!!!!! PS: Nobody will know how you got down there accept people who know the glitch. Have fun with the glitch.
