My book is about the Cold War. Particularly about the North Atlantic extension to the DEW line. The DEW line was a line of radar sites, as well as Niki Missile sites, across northern USA and Canada. They were installed coast to coast. Their purpose was to detect Soviet bombers that might be launching an attack on the USA from the north , (over the north pole). The DEW line extension ran from Newfoundland east to the Azores and was patroled by the Navy. There were four destroyers equipped with radar gear, and strung out about 250 miles apart in a line. The Navy flew patrol aircraft around the clock in a track around the ships. It was about a 13 hour flight round trip. There were four planes in the air 24/7 for over two years. On Feb.28, 1958 one of those planes disappeared without any warning, and no trace was ever found. Twenty two crew members were lost. My uncle was the radio man on that flight. The planes were Lockheed Super Constallations and were called Willie Victors (WV-2), and they were also equipped with radar gear. As well as trying to detect Soviet bombers, they were also looking for Soviet subs, ala "Red October."
