Nimrodnosewheel,
I agree, it was the "gas chamber" in the late 1970s, made from 12 by 12s, inside one of the hangars. Our Regiment instructor wasn't too bright and on one occasion he couldn't get the pellet to stay lit. Someone "helpfully" suggested he blew on it. He did, got down on his hands and knees to do so but stupidly took a deep breath for a second go. I think he was dragged out by his heels........
