A jet pack is a device someone wears that creates enough thrust, in a system somewhat similar to jet engines, to allow him or her to lift off the ground and fly. This flight thrust can be created in a number of ways, though a traditional âjetâ utilizes fuel to drive fans that allow for takeoff. More recent versions often use hydrogen peroxide and a catalytic reaction to create a stream of heated steam that provides thrust. A jet pack is typically an impractical device, as it is not only extremely unsafe but relies on small fuel supplies that cannot allow for prolonged flight.
The basic idea behind a jet pack is a self-contained unit that can be worn and operated by an individual person, which allows the wearer to fly. In reality, however, this concept has been quite difficult to achieve and even with advances in technology it remains largely impractical. There are a number of different forms in which a jet pack can be conceived and designed, though it typically includes a rocket pack worn on the operatorâs back, with different functions and controls to adjust flight. Most of these devices utilize a harness that ensures the pack remains secure on the operator, and some include a large frame that the operator fits into.
Double jumping just doesn't make any sense. I mean how do they just jump off of air.
Yes it does. Samus can do it in Metroid and so can Jackie Chan. I can't remember in which movie he did it but I remember him jumping on the right wall, pushing with his foot and jumping again to the left wall and then on the right wall and falling down and hurting himself. xD

of course it does. They jump off of the atoms in the air. It takes super skill to do that. They can't do it a second time because it upsets the balance of the atoms and makes them immpossible to jump off of for a couple seconds. Once you land, it's usually normal again. Basic Chemistry my friend.
There are lots of people who really believe that in case of a free falling elevator, it would save you to jump up a few seconds before hitting the ground.
Mythbusters did an episode on this a while back. Results indicated that you'll still go splat. The janitor just has a 5% easier time of cleaning you up.
