1954 ... 'Warning- Star'

... before modern, long-range radar, aircraft with large radomes flew constant patrols watching for Soviet bombers. This augmented what ground based radar there was. It was not until the early 1960's and the completion of the DEW Line that North American radar coverage was 'complete'.

... this was a fun project- built this from a photo of a scale model that a friend sent me.
... the basic aircraft was a converted Lockheed Constellation airliner.
