Fort Monmouth Radar-Visual — General's Alert
Signal Corps radar operators at Fort Monmouth tracked an unidentified target at 93,000 feet moving at estimated 700 mph with instant course reversals. A T-33 jet pilot simultaneously observed a disc from his cockpit. The incident alarmed General Charles Cabell, Air Force Director of Intelligence, who personally travelled to Wright-Patterson to demand Project Grudge be upgraded — directly leading to the formation of Project Blue Book.
