Black Ops Gunship MAJOR GLITCH!?! WTF?

Guys I know rage is a childish emotion but WTF I felt like slamming my effing PlayStation on the floor a moment a go! I got a gunship on Nuketown and was getting ready to spawntrap the bejeezus out of the other team and my effing gunship glitched up! It was moving on its own and whenever I tried to move it the screen would start freezing and not let me move it! Apparently this hasn't just happened to me, other people have reported it on forums. Some other people have experienced this. FOR CHRIST'S SAKE TREYARCH, FIX IT!!!! I ended up getting ONE kill with it people! The gunshop is an 11 killstreak and is supposed to be the best killstreak in the game, and after all the hardwork of earning it, I GET ONE EFFING KILL! Sorry I was just really pissed. Has anyone experienced this or have any idea why this is happening!?!
