When I was in CAF, Sketch, ScotchCAF and I were bored right before our Squad nights. A question was posed by ScotchCAF: "Can you fly an inverted B-26 through a bomber hangar?" With Sketch and ScotchCAF up, I did on the 2nd attempt. Long lost the film & SS when I reformatted my first PC that had this on it.
That was tougher than the Squad night itself.
