Lots more top secret projects......
I have also heard, and deduced for myself after inspecting a Stealth F-117A fighter at Beale Air Force Base, that the F-117A _also_ has hybrid propulsion and lift technologies, utilizing conventional thrust for public take-offs and landings, but switching to antigravity mode for extended cruising range, for lightning-fast maneuverability, and for shrouding the airframe in invisibility (by having its local counter-gravity field bend light around the airframe). The notorious extremely-unstable lift and forward-motion of the F-117A is merely temporary, until it moves into antigravity mode, where independent field propulsion provides stability. {Unfortunately for the pilot who went down in an air show over Maryland, his Stealth fighter was in conventional jet- thrust mode at the time.)
