Yup, the problem is definitely what we don't know we don't know. Mike Stacey of C and C was telling me at SOS that we've got it all wrong about the so-called Retired Pilot's badge, that it was in fact given out after so much time in service, and it was up to you what you wore--most army pilots evidently preferring the plane to the fat bird. I have seen two Urkunden to pilots in the summer and fall of 1918 awarding this badge while they were still in the service, but I have no other personal details. I now think (how many times have I reversed myself?) that it was just as unsoldierly to step out with a sloppy tarnished badge as it was to take a can-opener to it and alter its appearance. So Occam's Razor tells me its the shadow caused by UFOs crossing at that precise moment in front of the sun...or a "Retired" Pilot. Rgds John
