Back of a fag packet

If we were being green we'd replace all this nasty noisy stuff with helium balloons.

If we need 8E6lbs of thrust that's 3.5E9g. Now a 2l party balloon filled with helium will support about 2g so all we need are 1.75E9 helium balloons ... or, in honour of the great film, 1.75 Ups per launch and a big balloon pump ...
