AF Cambridge Research Center, Radar Systems Lsb, Electronics Research Div, electronics engineers, Alfred P. Furnish and Herbert J. Brun, and MIT electrical engineering senior Joseph Page, were in an observation tower on top of Great Blue Hill saw to the northwest two very thin flat, dull reddish orange squarish objects with no corners or "ovals pulled in at the waist" about 10-15 feet wide, with a lip around outer edges, fly wobbly in consistently undulating "swooping" motion in horizontal flight at about 2,000 foot altitude. Objects then climbed about 15° elevation at an estimated 240 mph, then flew away and disappeared due to distance. No trail or exhaust, no sound, visibility 70+ miles. (Unclear whether observers used 6x aircraft tracking telescope.)

Two blue-orange oval objects were observed by three AFCRL male witnesses in a town for 90 seconds (Furnish, Alfred P; Brun, Herbert J; Page,Joseph). No sound was heard.
