Project "SIGN" is responsible for the collection, investigation and interpretation of data relative to sighting of unidentified flying objects. At approximately 1205 local time, at an altitude of about 5500 feet, on a magnetic heading of about 120 degrees, just south of Anacostia Naval Air Station, an object was sighted ahead to the left and about 1100 feet below at a distance of about 1 mile. The flight path of the object was in approximately a south to north direction (exact opposite winds from North Northwest) and apparently followed a constant altitude. Pilot did not pursue object further because it was entering the prohibited flying area, W.S. No external rigid structure can be observed on the object.
