Correspondence Regarding Unidentified Flying Object Sighting - 6 March 1960

This collection of documents details an investigation into an alleged UFO sighting reported on 6 March 1960. The initial report, received by the Aerospace Technical Intelligence Center (ATIC) via a telephone message from Captain B. F. Dula of Military Flight Services, described a sighting by an Eastern Airlines pilot. The pilot reported observing a bright, flaring light in the southern sky near Evansville, Indiana, at 0224Z. The object appeared stationary and disappeared quickly. ATIC attempted to follow up on the report by contacting Eastern Airlines to identify the crew of the flight, which was identified as Flight 6403. However, in a letter dated 25 April 1960, Eastern Airlines responded to Colonel Philip G. Evans of the Aerospace Technical Intelligence Center, stating that they did not have an airplane numbered 6403, nor did they have a flight 6403 on the date in question. Furthermore, Eastern Airlines reported that they had questioned all pilots in the vicinity of Evansville on that date, and all denied having made such a report. Consequently, the investigation concluded that there was insufficient information to determine the nature of the object, and the case remained unresolved due to the inability to verify the witness or the flight details.
