Errrmm.. According to the shadows, the rear twin boosters (or whatever they are) aren't actually attached to the fusilage..:-)) LOL. It's SCI-FI!! The guns have anti-recoil mechanisms built in (based on the recently invented "inertia reducer"), the boosters are attached via "strange-force attractors", the centre of gravity is in fact dead-centre due to a combination of inertia-reducers acting on strahmge-force attractors, and it will work in space, too....:-)) Cheers, Diolma
