Offered is an original, United States Property marked Air Force flight suit. This suit, flying, very light is dark blue in color and is a size large tall. It was made by L. It dates to the 1950s and is period correct for the patch it bears on the right chest tying it to the 4925th Test Group, Atomic. The Group was discontinued on April 1, 1961, when Air Force Systems Command replaced Air Research and Development Command and components of its mission were distributed among other units. The 4925th was a significant and interesting unit that is worth your time to research, if you find yourself interested. This suit was obtained from the family of a very accomplished Air Force Colonel who recently passed away. He was given this suit by a member of the 4925th. The suit is offered exactly as pictured and shows very little wear for its age and use. The only real flaw I found is that the zipper on the left flank vent is off of one track. A pretty simple fix. A very interesting piece of Air Force history tied to a very interesting unit.
