First F-35B Vertical Takeoff Test

An F-35B test aircraft completes the first-ever vertical takeoff (VTO) at NAS Patuxent River, Md., on May 10, 2013. While not a capability used in combat, VTOs are required for repositioning of the STOVL in environments where a jet could not perform a short takeoff.  In these cases, the jet, with a limited amount of fuel, would execute a VTO to travel a short distance.
