Day ain't over yet.
My grandfather flew/worked on the RC-135E Lisa Ann / Rivet Amber during the Cold War. A portion of the plane (I believe the radar system) was built/serviced in Greenville, TX at E-Systems/L3, and he traveled to Alaska and Hawaii for test flights. He is nearly 100 years old and can still tell stories for days on this aircraft and his theories on it's crash.
Originally designated C-135B-II, project name Lisa Ann, the RC-135E Rivet Amber was a one-of-a-kind aircraft equipped with a large 7 MW
Hughes Aircraft phased-array radar system.[url=https://en.wikipedia.org/wiki/Boeing_RC-135#cite_note-rc135dotcom-15][15][/url] Originally delivered as a C-135B, 62-4137 operated from
Shemya Air Force Station,
Alaska from 1966 to 1969. Its operations were performed in concert with the RC-135S Rivet Ball aircraft (see below). The radar system alone weighed over 35,000 pounds and cost over US$35 million (1960 dollars), making Rivet Amber both the heaviest C-135-derivative aircraft flying and the most expensive Air Force aircraft for its time. This prevented the forward and aft crew areas from having direct contact after boarding the aircraft.[url=https://en.wikipedia.org/wiki/Boeing_RC-135#cite_note-DrBob-16][16][/url]
The system could track an object the size of a soccer ball from a distance of 300 miles (480 km), and its mission was to monitor Soviet
ballistic missile testing in the reentry phase. The power requirement for the phased array radar was enormous, necessitating an additional power supply. This took the form of a podded
Lycoming T55-L5 turboshaft engine in a pod under the left inboard wing section, driving a 350 kVA generator dedicated to powering mission equipment.[url=https://en.wikipedia.org/wiki/Boeing_RC-135#cite_note-DrBob-16][16][/url]
On the opposite wing in the same location was a podded heat exchanger to permit cooling of the massive electronic components on board the aircraft. This configuration has led to the mistaken impression that the aircraft had six engines. On June 5, 1969, Rivet Amber was lost at sea on a
ferry flight from Shemya to Eielson AFB for maintenance, and no trace of the aircraft or its crew was ever found.[url=https://en.wikipedia.org/wiki/Boeing_RC-135#cite_note-aviation-safety.net-17][17][/url]
