Project 10073 Record: Sighting near Porter, Indiana, 25 March 1966

This document contains a Project 10073 record regarding a UFO sighting that occurred on 25 March 1966 near Porter, Indiana. The primary witness was 1st Lt James R. Lindou of B Battery, 1st Missile Battalion, 60th Artillery. The object was described as a spherical, extremely maneuverable craft that changed colors from silver to yellow and pink to maroon. The sighting lasted between 40 and 45 minutes and was tracked via radar and telescope. Despite the duration and the involvement of military personnel, the official conclusion for the incident was 'INSUFFICIENT DATA.' The investigation, conducted by HQ Chicago ADS, noted that the report was poor because the initial notification to Truax Field lacked essential details, such as the names and addresses of witnesses. Furthermore, while the object was tracked on radar, no scope photographs were available for analysis. Correspondence between the 20th Air Division and TDEW/UFO confirms that B Battery, 1st Missile Battalion, 60th Artillery, explicitly advised that no photographs were taken. The documentation includes the original incoming message, internal correspondence requesting scope photos, and the final project record form.
