Secret Of The Airlift (Sixth of Seven) -- The Antenna of the CPS-5 is stopped momentarily to allow Sgt. Richard C. Olsen (left), Heresville, W. Va., to do a rush repair job. All the radar installations are kept in tip-top shape so that as little time as possible is lost in out-of-order delays. Operating 24 hours a day, the radar unit has been out only 28 minutes in the pat month. May 06, 1949. (Photo by ACME Photo Service).
