Check the listing for details. USAF Air Force Black Ops Area 51 413th Flight Test Squadron Bomb Cats Patch New. Condition: New. Listed at 6.95 USD. A detachment of the 413th, called the "Nutcrackers", continued to operate out of Groom Lake and the Tonopah Test Range. Daily flights in unmarked Beech aircraft shuttled members of the 413th to the secret bases each day. The 413th was responsible for a number of programs; code names included SUNDOWNER, ZIPPER, and IBIS DAWN. In May of 2004, the squadron was deactivated (although the unit designation was later transferred to a squadron formed from a detachment of the 46th Operations Group at Eglin Air Force Base in Florida). The remaining "Bombcats" assets became part of the Electronic Warfare Directorate, also headquartered at Edwards Air Force Base. This brand new patch is 3.5" in diameter and features a plastic backing. This patch comes from the published book:"I Could Tell You Then You Would Have To Be Destroyed By Me."
