"I think you are mistaken in assuming that BAM is an 'aviation related business'."
Sorry but a museum which houses airworthy aircraft and is located within the same accommodation which is also used by De Haviland Aircraft with their Vixen as well as World Aviation GA Maintenance and Parking I surly do rate as aviation related businesses.
I had no doubt that in due course this area would be used for airport expansion, maybe GA executive handling, but to loose it to a car park and at such short notice does seem like tribekey has a possible reason
