S.O.G. Headless Glitch

I need help

After you save Woods you will come to a part where you have to destroy 6 tanks. Do do this destroy farthest left tank of the last 3 tanks last. I'm not completely sure what causes the glitch. When you fire you TOW missile fire it under the building in a way it would hit the tank. The tank might shoot the missile. You will be loose control of the missile, but still hit the tank. You will be stuck to the missile fire screen and get to watch. Woods, Hudson, and Headless Mason greet Bowman.
