I think that was the hangar that I worked in for 5 years with 22 Sqdn Whirlwinds. We had the other half of the hangar and shared it with many Shacks over the years. Once a Shack was being pushed in and the chap on the tractor didn't stop in time, He later said he couldn't hear the "brakes" call as our sqdn radio was too loud. We later had some officers listening while "brakes" was called from various points in the hangar, it was hilarious to us, but we never had to switch off the radio afterwards.
