Correspondence regarding Rockdale, Illinois UAP sighting and O'Hare Air Force Squadron visit

This document collection contains a sighting report and subsequent correspondence regarding an Unidentified Flying Object (UFO) observed in Rockdale, Illinois, on January 2, 1965. The initial report, filed by the 61st Troop Carrier Squadron at O'Hare International Airport, describes a single, blue-greenish, circular object approximately two feet in diameter. The object was observed for 15 minutes at dusk, moving in an end-over-end fashion. The official conclusion reached by the Air Force was that there was 'Insufficient Data for Evaluation.' Following the incident, Dr. J. Allen Hynek of the Dearborn Observatory at Northwestern University engaged in correspondence with Major Hector Quintanilla of the Foreign Technology Division at Wright-Patterson Air Force Base. In his letters dated April 15 and May 25, 1965, Dr. Hynek discusses his meetings with Major Dellaorto at O'Hare Air Force Squadron. Dr. Hynek notes that Major Dellaorto was initially critical of the Air Force's communication regarding UFO reports, feeling that the military failed to provide feedback or sufficient information to investigators. Major Dellaorto suggested the implementation of a 'UFO newsletter' to share information between air bases to improve the quality of reporting and investigation. Dr. Hynek supported this idea, noting that such a system could provide necessary context for investigators and help address the problem of 'insufficient information' cases.
