The jetpack was an aerial personal transportation device in limited use across the multiverse. A jetpack offered a great degree of mobility in the air, though often at the personal risk of the user. Jetpacks were usually worn on the back, and controlled by a wrist-mounted device or through verbal commands issued into a visor or helmet. To launch, a jetpack funneled both air and fuel through miniaturized turbines. In the device's intake system, the air-fuel mix was ignited, providing the thrust needed to propel the wearer through the air. They were not reliable for use in zero, low or high atmospheric situations, since they required atmospheric gases to produce thrust[1]. The launch of most jetpacks was also accompanied by a cloud of exhaust - useful for quick getaways requiring a handy smoke screen.
