      In reference to your request regarding Plan 55:
      (1) Plan 55 was a new development for increasing Airways and Air
      Communications Service (AACS) message handling capacity was Western
      Union's
      Fully Automatic Teletype Switching Equipment. This permitted the
      transmission of up to 200 messages simultaneously, routing them
      according to
      address, recognizing traffic priorities, and making provision for
      expediting
      high priority traffic.
      (2) There were ten Plan 55 stations in the network: five in the US and
      five overseas. The first station was accepted 15 Nov 57; the last in
      May 60
      at Siegelbach, Germany.this was driven by of aircraft safety and
      better command and control of AF
      assets.
      (4) (4) These facilities were operated by AACS communication squadrons
      or groups, which, in effect, were the base communications
      organizations and
      not part of the Air Base Group.
      (5) In July 1961, AACS was redesignated the Air Force Communications
      Service (AFCS).

      (3) In effect, these automatic switching centers were expected to at
      least treble AACS message handling capability over the standard torn tape
      operation. It would money and be more efficient. As with most things AF,
