Project 10073 Record Card — Mattawamkeag, Maine, 10 March 1955

This Project 10073 record card documents a sighting that occurred on March 10, 1955, in Mattawamkeag, Maine. The event involved a single, extremely bright object observed by a commercial pilot and a Ground Observer Corps (GOC) observer. The witnesses reported that the object was red, yellow, and green in color and was seen falling toward the horizon for a duration of three to four seconds. The GOC observer noted that there was no other aerial activity in the area at the time of the sighting. The official conclusion reached by the project was that the object was likely an astronomical phenomenon, specifically a meteor. The record card notes that the investigation was hindered by a ten-day delay in receiving the initial report. Because of this delay and the perceived improbability that further investigation would yield useful information, no follow-up investigation was authorized. The document serves as a summary of the incident and the administrative decision to close the file without further inquiry.
