Five Green Spheres In V-Formation California 1953 USAF T/Sgt. George Beyer saw five 25 ft green spheres fly in V-formation, then change to trail formation at which time the end objects turned red. This case ground/visual was evaluated as UNIDENTIFIED by Project Blue Book. This case may tie into the pilot sighting and jet chase at El Toro Marine Air Base a few hours later, which can be read about here: Eltoro Marine Base, California
