It was an orphan all right, unloved and unwanted! Too big to be accommodated inside the existing museum it would require a bespoke building to shelter it. Not a feasible option for what was after all 'only' a transport aircraft, or so I imagine that was how the thinking went. The MOD wanted rid of it, the museum didn't want it; its fate was sealed. That H&S considerations resolved the dilemma says it all. A lot of railway infrastructure went the same way in the 50's. Once BR had blown up a viaduct that was 'unsafe' simply as a result of not being properly maintained, then that line joined all the others that were already 'cancelled'.
