Scott Oosting (L) and Dave Tuxbury (R) go airborne with jetpacks providing human flight experiences in Key West, Florida, June 24, 2011. The flight apparatus is tethered by a 30-foot hose dragging a tiny boat with a pump that uses seawater as propellant. During training, the instructor remotely operates the vehicle, but as the participant becomes more proficient, he gains more control. Photo taken June 24, 2011.
