Guns on Millenium Falcon: behind the scenes?


Sr Member
Just got through watching SW on Spike's all day SW marathon and I got to thinking. At one point or other I think I have read or seen just about every behind-the-scenes thing ever made on SW. But I have never seen anything on the TIE fighter attack on the Falcon during the Death Star escape.

I am particulary interested in the guns and gun chairs. I have always assumed that the chairs must have been on some kind of swivelling teeter totter system with stage hands moving the chairs as they swing from side to side...But I have NEVER seen or read anything on the making of this sequence.

Can anyone confirm or deny this hypothesis? Or have any behind the scenes pics or info?
