When I was going through -38s in UPT, we got a call that a Cougar that had lost its canopy and was in our area. The IP wanted someone to check him over to see if there was any damage. We, in our 'white whale', eased up on him wearing his dark blue. It was a contrast. No damage noted so we both went our own ways. Never knew what happened to cause the canopy loss or where they recovered but funny.. two guys sitting in a swept wing machine with no canopy.
