There is at least one Sea Harrier flying in private hands in the USA, so maybe this will work, but I just hope they keep VTTS Fleming well away from it.
As for not letting it hover in displays, well that would rather defeat the purpose, and they are a long way yet from having any sort of flight, let alone a display sequence.
I for one would love to see a Harrier display at UK airshows again, so I will watch this project with interest.
