Sorry for the late hour, been dealing with a VERY stubborn stopped up kitchen drain. I check all three major mags, Flying Models, American Aircraft Modeler, and M.A.N and no Preston Wilson on any of the covers of the September, October, or November issues. NATS coverage is traditionally ion the November issues of all three magazines. I didn't get to go through AAM or MAN, Flying Models didn't have his picture in the coverage inside either. The '71 NATS was the 40th Anniversary, and at Glenview NAS, so mention that to him and see if that jives with his memory. Like I mentioned before, my experience with looking this stuff up for people is that they almost never remember it correctly. After all, that was only 49 years ago! One guy swore that his picture was on the cover, but turned out it was inside the copy of the control line column. Tell him to try again keep us posted.
Type at you later,
