Guys,
Thanks for the replies, sounds as if unless the author puts in comments it's going to take some detective work.. which is OK, after all I'm doing this for the fun of it anyway! The idea about looking for the smallest radius is very good, it makes sense.
Russ, glad you are an airplane fan, I've spent some time with Phantom's, but I was around long enough that I was there for the first introduction on both Tomcats and Hornets. I was maintenance chief when we converted VF 213 from F4N's to F14A's, later I stood up the first East Coast Hornet squadron (VFA-131) and moved them from the training base in California to Cecil Field (Jacksonville) FL. I was in St. Louis for the first flight of a Hornet! That was a long time ago, 1978, and it seems like a lifetime LOL.
Thanks again Guys
Chief
