It Has Been Discussed, But Just to Clarify

Harrier ownership - is it LEGAL? I want to see if I can acquire a Sea Harrier FRS.1 (consider the variant, this version is not a killing machine like the FA.2 or AV-8B II and people have acquired "tame" aircraft, such as the DeHavilland Sea Vixen and North American F-86 Sabre). Furthermore, once acquired, is it legal to fly (and eventually VTOL) it? I believe because of its poor glide rate, it is not allowed to fly over London.
