The velcro idea was really a plot to pee off the flying clothing squippers. In the early 80's we only had to sew the badges onto flying suits. Then after 1982 it was, sew velcro onto badges. Trim velcro neatly around badge. Get the opposite piece of vlcro. Trim to shape. Sew onto flying suit, in the correct place. Attach velcro clad badge to velcro clad flying suit.
AFAIK this has continued to this day.
