Was it the building or the planes themselves. Well worth a visit, The Canadian Warplane Heritage museum sports a large collection of flying vinatge aircraft and apparently a few permanent visitors.
At their old building, Hanger #4, there were reports of people hearing voices and the sounds of aircraft powering up even though it was impossible to have been happening. The museum now has it's own building and has moved it's incredible exhibit.
Did the "ghosts" come with the aircraft or stay in Hanger 4? We are still waiting for a recent report.
