ATLANTIC OCEAN (Oct. 18, 2010) Aviation Boatswain's Mate (Equipment) Airman Daniel Booher, from Bristol, Tenn., guides an F/A-18E Super Hornet into the catapult shuttle aboard the aircraft carrier USS Enterprise (CVN 65). Once the catapult fires, the hold-back breaks free as the shuttle moves rapidly forward, dragging the aircraft by the launch bar. The aircraft accelerates from zero (relative to the carrier deck) to approximately 173 mph in about 2 seconds. Booher, 27, has been trained to constantly look for danger on the flight deck. Aircraft are constantly moving as they are staged for launch and the opportunity for serious injury is ever-present. (U.S. Navy video/Released)
