Seems a bit strange that they would keep this piece of history airside when they could probably have put it somewhere near LHR and charged a few quid to let people see it. They could even have turned it into a restaurant or something. Leaving her to fall to bits, especially in the middle of LHR, just seems like such a waste.
G-BOAC is kept in exactly that kind of condition at MAN.
