Interesting how the Harrier (Ooops) was flown with obvious confidence, verve even whereas the F-35 was kept very much on the leash..
Right now the F-35 fleet (all three variants) have a restricted flight envelope, imposed on them after aircraft "AF-27" (a USAF F-35A) had an engine component failure during a take-off roll last year. Unfortunately - but pragmatically - the aircraft is especially 'G' limited right now however this will expand over the coming year.
