Project 10073 Record Card — Sighting Report, Boston, Massachusetts, 1 June 1954

This document details a sighting report filed under Project 10073 regarding an unidentified aerial phenomenon observed on June 1, 1954, near Boston, Massachusetts. The witness, a TWA pilot, reported observing a 'milky white' object that appeared 'balloon-like' and 'plastic-like' while flying. The observation lasted between five and eight minutes. The witness noted that the object was at a very high altitude and did not produce any sound. The pilot initially contacted Boston Tower and later received information from TWA-Boston that Grenier Air Force Base had released a balloon at 0430 hours. The pilot concluded that the object he observed was likely the balloon released by the Air Force base. The documentation includes a formal letter from the Air Technical Intelligence Center at Wright-Patterson Air Force Base, dated June 23, 1954, thanking the pilot for his report and requesting the completion of a technical information sheet. The pilot's completed questionnaire provides further context, noting that he was flying at the time of the sighting and that the object appeared to move away from him. The weather conditions at the time were described as clear with a slight breeze. The official conclusion recorded on the project record card confirms the identification of the object as a balloon released by Grenier AFB.
