Hi
Do not know if this helps but I grew up adjacent to LHR in the late 50s through 60s. As I recall there was never a crash outside the airfield boundary on the north side where all the hotels are located along the A4.
However one of the hotels-its current name escapes me as I no longer live around there but it used to be called the Aerial. It is ( was -- cos it might have ben renovated or extended) a disctinctive circular shape. As far as I knowit was built on the site of a very old pub frequented by travellers and gentlemen of the road in the days when LHR was Hounslow Heath and a stagecoach wasnt a dodgy bus company.
I cannot rememeber the name of the pub but given its reputation and the murky past of that area as a haunt for highwaymen , footpads and other 18th century exotic criminals I think its quite likely that theres a haunting legend associated with it
