AI-Generated Summary
A C-121 flight crew over Japan reported an unidentified object leaving blue-white streaks on May 15, 1961. The Air Force concluded there was insufficient data to reach a valid conclusion.
This document is a Project 10073 record card and an associated incoming Air Force message regarding an unidentified aerial phenomenon reported on May 15, 1961. The sighting occurred at 1554Z at coordinates 3526N 14155E, involving a C-121 flight (548) departing from Tachikawa Air Base, Japan. The crew observed an object leaving long blue-white streaks. The report explicitly notes that the object did not appear to be a meteor, but rather resembled a missile or other space vehicle burning up upon re-entry into the atmosphere. The object was described as being at an extremely high altitude and moving at a high speed. The aircraft was flying in clear conditions above a solid undercast. The report was received by headquarters on May 16, 1961, at 0431Z. Because of the time lag between the event and the receipt of the report, as well as the lack of sufficient data, the military authorities determined that no evaluation could be made and no follow-up action was taken.
