Project 10073 Record Card — Dorchester, Massachusetts, 30 May 1964

This document contains a Project 10073 record card and associated correspondence regarding a UFO sighting in Dorchester, Massachusetts, on May 30, 1964. The civilian witnesses reported observing a bright white, round object moving slowly across the sky in a shallow zig-zag pattern for approximately six minutes. The object was described as being high in the sky, appearing the size of a 'bee-bee held at arms length.' The witnesses noted the object moved from a position overhead to beyond the horizon in the southeast. In a follow-up letter dated June 5, 1964, Major Maston M. Jacks of the USAF Public Information Division informed the witnesses that their observation had been identified as the Echo I satellite, which was positioned 88 degrees above the horizon at approximately 9:51 p.m. EST on that date. The file also includes earlier correspondence from the same individuals requesting information on unidentified flying objects and pilot training manuals for the T-38 and T-37 jet trainers, as well as an earlier request regarding the F-51 Mustang.
