Project 10073 Record Card — Bartlesville, Oklahoma, 31 October 1957

This document consists of a Project 10073 record card and associated teletype reports regarding an unidentified aerial object sighting on 31 October 1957 at Bartlesville AFS, Oklahoma. The sighting was reported by tower personnel, including S/Sgt Loyd Stevens, A/1C Melvin O. Crader, and A/1C Bernard M. Srodwlski, all of the 796 AC&W Squadron. The witnesses described a single, round, silver object, approximately the size of a baseball, which appeared to be climbing. The object was observed for one and a half hours using 7x50 binoculars. The tower operator initiated the observation after receiving four or five calls regarding the object. The report notes that two salvos were scrambled from Tulsa, but no contact was made. Weather conditions were reported as surface calm. Capt. Froy V. Arndt, Director of the 796 AC&WO, concluded that the object was likely a weather balloon based on its appearance, course, and speed. This assessment was concurred with by evaluators who noted that while the time of day was not explicitly provided in the initial report, the physical description was consistent with a weather balloon.
