White UFO seen like Echo I in Baltimore

Summary

A pilot reported a white object resembling a star during a flight near Baltimore, Maryland, on February 21, 1961. The object was observed for 10 minutes at an altitude of 31,000 feet, moving in a 060° magnetic direction, about 35° above the horizon. The pilot, noticing a possible obstacle in his path, asked air traffic control, who found no activity in that area. Although a weather balloon or the Echo I satellite were considered, no confirmation was received.

The weather report indicated clear conditions with no storms or visible obstacles. The object showed no signs of being an aircraft or a known astronomical phenomenon. Attempts to contact the pilot for more details were unsuccessful. The case was classified as "Echo I," referring to a series of U.S. satellites, but without definitive confirmation.
