    When Analogue Ruled OK.
    From: David Pike
    Date: 2022 Nov 6, 13:40 -0800

    A colleague sent me the link to this film of the mainly analogue inertial navigation system used in the RAF’s ‘Blue Steel’ stand off missile. Elliott Inertial Navigation System for Blue Steel (principles & manufacture) :: Rochester Avionic Archives.  It’s amazingly detailed and must once have been classified SECRET.  Its core might now be replaced by a chip the size of a match box, but my word didn’t they lovingly work on it.  DaveP
