In his defense we had the green bag name tags that showed Lt Smyth's RCAF wings. The Col was ready to ream Lt Smyth (and those of us enjoying it) out then saw the Canadian wings. Most of us were smart enough to run into the cargo bay to laugh.
The look on the colonel's face was priceless, cherry red with white bug eyes. Then Lt Smyth smartly saluted again as the Colonel departed!!
I love it! Thanks for the story!
