Alex Dietrich is a retired U.S. Navy Lieutenant Commander who flew the wingman F/A-18F Super Hornet during the 2004 USS Nimitz encounter — the same event described by David Fravor — making her the primary corroborating aircrew witness to that incident.12 She remained silent about the event for approximately 17 years before giving her first on-camera interview to CBS News 60 Minutes in May 2021.1
Naval Career and Credentials
Dietrich graduated from the Illinois Math and Science Academy, earned a B.S. in Civil Engineering from George Washington University on an NROTC scholarship, and later completed an MBA from GW's School of Business.3 She also holds a Defense Language Institute certification in Dari.4
During 20 years of active-duty service, she became one of the first female F/A-18 pilots in the United States Navy, logging more than 1,250 flight hours and 375 carrier-arrested landings.5 She completed two combat deployments supporting Operation Iraqi Freedom and Operation Enduring Freedom, flew 206 combat missions earning an Air Medal, and served a boots-on-ground deployment to Ghazni Province, Afghanistan, for which she was awarded a Bronze Star.35 She retired as a Lieutenant Commander after separating from active duty in 2020.
The 2004 Nimitz Encounter
On November 14, 2004, Dietrich and Fravor were vectored by the USS Princeton to investigate anomalous radar contacts that Princeton's Aegis operators had reportedly been tracking for approximately two weeks — objects said to descend from above 80,000 feet to near sea level.2 Each aircraft carried a Weapons System Officer, giving four total aircrew as witnesses to the event.
Fravor descended in a circular pattern toward the object while Dietrich orbited above at altitude.1 Both pilots reported observing an oblong, white, Tic Tac-shaped object approximately 40 to 46 feet in length with no visible wings, markings, or exhaust plumes, hovering above a churning patch of disturbed ocean.12 Dietrich described the object as having "no predictable movement, no predictable trajectory."1 When Fravor maneuvered toward it, the object accelerated away so rapidly it appeared to vanish, and Princeton's radar reportedly reacquired it roughly 60 miles away within seconds.2
Dietrich stated she felt "the vulnerability of not having anything to defend ourselves."1 Both pilots gave debriefs and written accounts immediately after landing; no formal investigation followed.1
Going Public
Dietrich did not speak publicly about the encounter for approximately 17 years. Her first on-camera interview aired on CBS News 60 Minutes on May 16, 2021, timed to coincide with the forthcoming government UAP report.1 She explained her decision to come forward: "Because I was in a government aircraft, because I was on the clock. And so I feel a responsibility to share what I can."1
She stated she also came forward to reduce the stigma faced by military personnel who report UAP encounters.1 She has since participated in multiple media interviews and podcasts. She was not among the witnesses who gave sworn testimony at the July 26, 2023 House Oversight UAP hearing — that panel included Fravor, Ryan Graves, and David Grusch — though her account was referenced during those proceedings.2
Post-Military Career
After leaving active duty, Dietrich taught leadership, ethics, and critical thinking at Georgetown University and George Washington University, and served as a Military Professor at the U.S. Naval Academy's Department of Leadership, Ethics and Law.34 Since 2022 she has been an adjunct instructor in the Lockheed Martin Engineering Management Program at the University of Colorado Boulder, and from 2023 has held the title of Scholar in Residence in that program.3
Evidentiary Context and Skeptical Notes
Dietrich's account is corroborated by the other three aircrew in the two-aircraft flight, by the Princeton radar operators who tracked the anomalous contacts, and by the declassified FLIR1 infrared video — captured later that same day by a different aircrew and officially acknowledged by the U.S. Navy in 2020 as authentic and unidentified.6 The combination of radar, visual, and infrared sensor data across multiple independent witnesses is considered one of the stronger chains of corroboration in any UAP case.
Skeptics have offered several counterpoints. Researchers at Metabunk have proposed a cruise missile hypothesis — arguing that the object's characteristics and brief observation time are consistent with a cruise missile rather than an anomalous aerial object.7 Author David Halperin has raised questions about inconsistencies in Dietrich's recollections over time and suggested that time-dilation sensations she mentioned may reflect perceptual distortion rather than anomalous object behavior.8 Some analysts note the visual observation lasted only a few minutes, leaving open the possibility of misidentification of a classified U.S. or foreign platform, though no government source has publicly claimed ownership of the object.89
