OK Air Force, how bout give us anon's a nod and tweet some pics showing these 1950's fighter's with the FU tail numbers! Wish I could have found a pic showing FU-017 You fly boys had a sense of humor way back then, I can envision coming along side a MIG and motioning to your tail, "Hey Comrade, see my tail numbers? They say it all"
So what do you say AF? Please give us a tweet to lift us up?? We could use a OMG laugh bout now. Pleaseeeee ;-)
(Couple pics are screen grabs from a 1950's movie named GOG)
