The X-35B lifts off the hover pit with its nozzle vectored for short-takeoffvertical-landing. To convert the engine’s operation from conventional takeoff to STOVL, the pilot moves a lever back about an inch. This opens four sets of doors behind the cockpit, allowing air to flow through the lift fan and starting the nozzle moving through its full range of travel. Simultaneously a clutch engages, transferring power from the engine to the lift fan.
