Project 10073 Record Cards and Correspondence — McKinney, Texas, April 1956

This document consists of a series of reports and record cards regarding Unidentified Aerial Phenomena (UAP) observed in McKinney, Texas, in April 1956. The primary report is a letter dated May 14, 1956, from Captain Roy F. Hall (Retd.), a local Weather Bureau observer, to the Director of Air Force Intelligence. Captain Hall details a sighting on April 4, 1956, where he and an amateur astronomer observed a large, stationary, silvery object through telescopes. The object, estimated to be over 200 feet in diameter and at an altitude of 100,000 feet, maintained a fixed position relative to the planet Venus for several hours before disappearing at sunset. Hall notes the object had a raised band around its middle, did not rotate, and appeared to be made of translucent, silvery rubber. He explicitly rules out weather balloons after contacting the Fort Worth Weather Bureau. The document also includes reports of two subsequent incidents. On April 6, 1956, witnesses reported a smaller, five-to-eight-foot silvery object that descended into a field before taking off at high speed. On April 13, 1956, Captain Hall observed two red lights moving at high speed, while another witness reported three pale blue lights. The Air Force Project 10073 record cards categorize the April 4 sighting as 'Unknown' and the April 13 sighting as a 'possible meteor.' The document includes sketches of the April 4 object, which show a distinct, band-like structure. Captain Hall emphasizes his skepticism regarding 'flying saucers' but provides the data for official review.
