Some time back I acquired a CWU-27 nomex flightsuit that had belonged to a USAF fighter pilot. IT has a 1980 contact date in the label. What was unique is that all the patches and rank have a black leatherette backing. The material was cut a little larger than the patch to give it a black edgingh and was sew to the patch and then sewn to the flight suit. The only velcro is for the name/wing block. I have attached a picture of the left shoulder which has a USAF Fighter School Graduate patch, plus the colonel's rank (encased in clear plastic) also has the leatherette backing.
I had come across this before with some US Air Force Europe (USAFE) patches. Does anyone know if this practice was Air Force wide at one time or limited to USAFE? Thank you.
