Project 10073 Record Card — Sighting in Baltimore, Maryland, July 1957

This document consists of a Project 10073 record card and an associated teletype report regarding an unidentified aerial phenomenon sighting that occurred on July 28, 1957, at 0634Z in Baltimore, Maryland. The witness, identified as T/Sgt Muttelman of Detachment 5, 4715th Ground Observer Squadron, described observing a single object that appeared white, green, and orange. The witness, noted as an aircraft enthusiast, estimated the size of the object to be that of a pea held at arm's length. The object was observed moving in a south-southwest (SSW) direction and the sighting was described as momentary. The official conclusion recorded on the card, based on a limited investigation by Detachment 10, suggests that the object was likely a meteor. However, the teletype report includes a handwritten note providing additional context, suggesting that the location of the sighting was near the Westminster, Maryland airport and within the Red 33 traffic airway. This note posits that the lights observed—described as flashing green, white, and orange (red)—under hazy, overcast conditions were likely an aircraft rather than a meteor. The report confirms that no photographs or radar contact were associated with the event.
