The briefing includes additional details regarding that incident, including a characterization of the meteorological conditions and sensing capabilities of nearby U.S. military collection systems. The briefing states that a radar system aboard USS Gyatt, a guided missile destroyer operating in the vicinity, detected a contact tracking more than 3,800 knots (approximately 4,373 mph) over a period of 21 minutes. The briefing contains visual estimates regarding the phenomenon’s apparent capabilities from the pilot of an F-8 Crusader who was present during the incident.
