Chad Underwood is a former officer of the United States Navy (USN) who served with Strike Fighter Squadron 41 (VFA-41) as a weapon systems officer (WSO)1. On 2004-11-14 his crew formed the second F/A-18F section from the squadron airborne that day2, launching after David Fravor’s flight returned to USS Nimitz (CVN-68) from its encounter with the object at the centre of the 2004 USS Nimitz UAP encounter3. Before launch, Fravor’s flight crew met Underwood’s crew in the paraloft aboard the carrier and passed on what they had seen4, asking them to try to see and record the object5. Underwood went on to record the forward-looking infrared (FLIR) video of the object from the encounter6, using the Advanced Targeting Forward Looking Infrared Radar (ATFLIR)7.
Underwood’s flight departed the carrier, climbed to altitude, and separated to begin the training portion of the sortie8. He recalled that it was a clear day, with no clouds and a discernible blue horizon9, and placed the FLIR tracking event at approximately 15:00 local time10. The flight checked in with the E-2C Hawkeye before proceeding south to the southern combat air patrol station11, flying at approximately 6,100 metres on a max endurance profile at approximately 560 kilometres per hour ground speed12. All onboard systems were functioning normally, with the radar in standard search mode and the FLIR in L+S slave mode13, and the aircraft had no radio interference and access to the Link-16 network14. Initial radar tracks placed the object approximately 55-74 kilometres to the south15. Underwood attempted multiple times to transition the radar to Single Target Track mode, but it could not achieve a lock16, and the object defied the crew’s attempt to obtain a good radar lock17; he observed no jamming cues, such as strobe or champagne bubbles, or any normal electronic-attack indications, on his radar18, and the radar could not gather enough information to build a single target track file19. On the FLIR display the object appeared at 0 degrees angle track antenna and approximately -5 degrees elevation20, and Underwood estimated it to be co-altitude with his aircraft or a few thousand feet below, between approximately 4,600 and 6,100 metres21. It appeared stationary on the display, with no discernible movement other than closure resulting from his own aircraft’s movement22, then began moving out of the FLIR field of view to the left; Underwood made no attempt to slew the sensor and lost situational awareness of it23. The Anomalous Aerial Vehicle (AAV) appeared solid white, smooth, with no edges, uniformly coloured, and with no nacelles, pylons, or wings24. According to the Nimitz Carrier Strike Group (CSG-11) AAV Incident Report, a FLIR image in White Hot Mode captured by Underwood’s aircraft showed a faint bright object against a dark background25, while a Black Hot mode image showed a faint dark object against a lighter background26. Underwood testified that he could not confirm the object he tracked on FLIR was the same one described by Fravor’s flight, as he never had visual contact and saw it only via the sensor27; he reaffirmed that all systems on his aircraft were functioning normally throughout28. The flight continued its training mission with no further contact with the object29, and the section returned to the carrier for a normal approach, landing, and shutdown30.
Other published accounts add further detail to the intercept. Underwood’s aircraft was fitted with an Advanced Targeting Forward-Looking Infrared (ATFLIR) targeting pod31. As his crew reached the point where Fravor’s flight had last seen the Tic Tac, it was still waiting there32. David Fravor said that when the crew’s radar tried to lock onto it, there were clear indications of deliberate jamming, which could be perceived as a hostile act, technically an act of war33. The crew eventually locked onto the object using the ATFLIR pod’s infrared mode, which showed it as a white object against a black background34. Underwood said the thing that stood out to him most was how erratically it was behaving, with changes in altitude, air speed, and aspect unlike anything he had encountered flying against other air targets35. He said its behaviour was not physically normal, noting that aircraft, manned or unmanned, still have to obey the laws of physics and require some source of lift and propulsion, which it did not appear to have36, and that it went from approximately 15,000 metres to approximately 30 metres in altitude within seconds, which he said is not possible37.
Underwood’s crew met in the Carrier Intelligence Center (CVIC) aboard USS Nimitz (CVN-68) and debriefed38. Underwood said CVIC personnel attempted to collect his tapes but he refused39. His crew then proceeded to their ready room and debriefed with Fravor and his flight40. According to Imminent: Inside the Pentagon’s Hunt for UFOs, both Underwood and Fravor’s flight, including Jim Slaight, reported that the object vanished instantly over the horizon41. The pilot of the aircraft carrying Underwood did not have a vivid recollection of the event and did not consider it a big deal at the time42. For about two days afterwards, the air wing’s flight schedule carried joke comics on its back page, styled after Men in Black, naming Fravor and Underwood as protecting the Nimitz battle group43. According to In Plain Sight, the FLIR video was downloaded when Underwood returned to the carrier, and conspiracy theories abounded among crewmen who saw it while the ship was still at sea44. Underwood was not asked to sign any non-disclosure agreement regarding the encounter and said he was uncertain how far up the chain of command the reporting went past his commanding officer45. When asked, he could not confirm any physiological or psychological feelings out of the ordinary, only a feeling of confusion during the event46. He answered a few questions in a phone call with someone from the North American Aerospace Defense Command (NORAD) soon after landing47; according to Luis Elizondo, a NORAD investigator put a few questions to Underwood, and no other internal agency investigated the encounter48.
Luis Elizondo described Underwood as an otherwise serious and focused pilot who never indulged in flights of fancy49. Ross Coulthart said the manoeuvres filmed by Underwood implied that someone, somewhere, had achieved a technological breakthrough demonstrating that such manoeuvres were actually possible50. Underwood later discussed the encounter in a 2019-12 New York Magazine interview with Chad Underwood.
