When I worked at British Aerospace Dunsfold in the late 80s/early 90s, it was a hard rule that nobody got to sit on an ejector seat unless that had been training in its use. I am surprised that it's not an absolutely universal rule. The consequences of inadvertently triggering an ejection while in the maintenance hanger are pretty ugly.
