air test

The Air Force Test Center (AFTC) is a development and test organization of the United States Air Force. It conducts research, development, test, and evaluation of aerospace systems from concept to deployment. It has test flown every aircraft in the Army Air Force's and the Air Force's inventory since World War II. The center employs nearly 13,000 people, and controls the second largest base in the Air Force.On 6 July 2012, the previous Air Force Flight Test Center (AFFTC) was redesignated as the Air Force Test Center (AFTC). Up until July 2012, the AFTC consisted of two subordinate wings. The 95th Air Base Wing (95 ABW) provided installation support for all units on Edwards Air Force Base while the 412th Test Wing (412 TW) conducted aircraft testing and evaluation at Edwards. In July 2012, the redesignated 96th Test Wing (96 TW), an amalgamation of the former 96th Air Base Wing, the former 46th Test Wing and the former Air Armament Center at Eglin Air Force Base, Florida, and the Arnold Engineering Development Complex at Arnold Air Force Base, Tennessee, also came under control of the AFTC.

    Do you pressure test?

    How many domestic plumbers on here actaully pressure test their new pipework after fitting. If a fitting failed and flooded a customers house, will the insurance pay up? Mind you there would be no proof that you didn't pressure test.
