UFOB Index Card AISS-UFOB-406-56

This document contains a collection of records regarding an Unidentified Aerial Phenomena (UAP) sighting reported in Newburgh, New York, on October 13, 1956. The primary witness, a mail carrier, observed a very bright, circular object that appeared to be the size of a basketball to the naked eye. The witness reported that the object exhibited pulsating behavior and moved in up, down, and sideways directions for approximately 20 minutes. The witness also noted that the object changed in size from that of a basketball to the size of a pinhead within one minute. The sighting occurred in clear weather conditions at approximately 10:30 PM local time. The witness, who was walking a dog at the time, noted that the object was visible to others in the area, including reports from Cedar Grove and Orange, New Jersey. The Air Force investigation, conducted under Project 10073, concluded that the sighting was likely caused by a weather balloon. The official response to the witness emphasized that a significant number of weather balloons were launched in the 26th Air Division area during that period. The Air Force further explained that balloons at high altitudes can appear to have pulsating shapes and colors due to the reflection of sunlight on the balloon's surface, even when the ground observer is in darkness. The document includes the original UFOB Index Card, a Project 10073 Record Card, the witness's completed U.S. Air Force Technical Information Sheet, and subsequent correspondence from the Air Technical Intelligence Center to the witness, addressing his questions about the nature of the object and the reporting process.
