Project 10073 Record Card — Redmond, Washington, March 1957

This document consists of a Project 10073 record card and associated teletype messages regarding an unidentified aerial phenomenon sighting on March 26, 1957, near Redmond, Washington. A civilian witness reported observing a kite-shaped object, oriented vertically, which appeared to be rotating clockwise. The object was described as dull grey and silver in color and was observed at an altitude between 1400 and 1600 feet for a duration of approximately one minute. The object was also sighted by a student pilot in an observing aircraft. The report notes that the object was initially mistaken for a jet, but its specific behavior—rolling and rotating—prompted further scrutiny. The official conclusion reached by the Air Technical Intelligence Center was that the information provided was insufficient for a formal evaluation. While the vertical orientation and color were noted as characteristics potentially indicative of a balloon, the lack of data regarding the heading or speed of the observing aircraft, combined with the unusual flight characteristics, prevented a definitive identification. The report was transmitted from the 25th CADD at McChord Air Force Base to the Air Defense Command at Ent Air Force Base, Colorado Springs, and the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
