Project 10073 Record Card: Wellsboro, Pennsylvania Sighting, 11 July 1957

This document consists of a Project 10073 record card and associated teletype reports regarding an Unidentified Aerial Phenomenon (UFOB) sighting that occurred on July 11, 1957, in Wellsboro, Pennsylvania. The report details the observation of a single, round, white object, described as being approximately the size of a basketball. The witness, identified as Captain Sidney Smith of the Harrisburg GOC Filter Center, observed the object for a duration of one hour and fifteen minutes. According to the report, the object remained at a fixed altitude for 45 minutes before eventually fading in the west. The weather conditions at the time of the sighting were reported as clear, with surface winds blowing from 270 degrees at 13 knots. The report notes that the object would have drifted to the east or southeast based on wind conditions. The official conclusion recorded on the card is that there was insufficient data for a definitive evaluation, though the teletype report explicitly suggests the object 'could be weather balloon.' The documentation includes routing information to various military commands, including the 648th ACWRON, the Air Technical Intelligence Center at Wright-Patterson Air Force Base, and the 4602nd AISS at Stewart Air Force Base, reflecting the standard military procedure for handling such reports during this period.
