I remember your :jet pack thread.  One day you've got a raw jet pack, and just a day or so later, it's completely painted!  Unbelieveable!:thumbsup::thumbsup:




A :jet pack flies like a rocket, not an airplane, so I can say this because it's true for almost all rockets that can lift something off the ground: the great majority of the weight will be the fuel and oxidizer.
