The supporting Nimitz accounts concern different positions and different stages. Alex Dietrich observed the first encounter from the covering aircraft. Kevin Day's later account concerns Princeton's tactical picture and the decision to investigate. Chad Underwood recorded the subsequent airborne infrared sequence. Comparing their records explains why visual descriptions, radar recollections and released video cannot be assigned collectively to every witness. David Fravor's lead-aircraft account is reviewed in his own dossier.
Pilot of the covering F/A-18F during the first visual encounter
Alex Dietrich
The encounter from the covering aircraft
In her published 2023 interview with Peter Bergen, Dietrich describes an unexpected object and the difficulty of explaining what she saw. The programme also incorporates earlier interview excerpts: she describes a white, oblong form moving unpredictably while her aircraft remained above and Fravor descended. Her access was to the first visual encounter, rather than Underwood's later recording flight.
Dietrich distinguishes reporting an unfamiliar observation from determining its nature. She says she lacks a settled explanation and presents her response in terms of an aviation duty to report. This position differs from Fravor's stronger technological interpretation without removing the shared basis of their reported visual experience.
Evidence review
High cover provides a different view of the lead aircraft and apparent target. Agreement about a white oblong object is meaningful supporting testimony, but their accounts concern a shared encounter and subsequent reporting history. They do not supply two independently archived, synchronised instrument measurements.
The anonymously published short summary also identifies high cover and loss of visual contact, but does not name Dietrich. Its statement about haze cannot be assigned to her as a verified, signed account written at the time of the November 2004 encounter. Her attributable interview and the unsigned reproduction have different provenance.

2021: speaks publicly in the CBS reporting associated with the Nimitz witnesses.

Princeton Operations Specialist Senior Chief with air-intercept-control duties
Kevin Day
The shipboard reporting account
SCU's 2019 investigation presents Day's account of unusual display contacts, concern about interference with a planned exercise and a recommendation that a contact be investigated. Its interview ledger identifies Robert Powell's first interview with him as 15 January 2018. This is a retrospective reporting source, rather than a surviving 2004 statement or an original radar-data file.
The report reproduces a discharge form and a Princeton fitness report identifying Day as an Operations Specialist Senior Chief and documenting air-intercept-control duties. Those records support the relevance of his naval role; they do not verify the reported contact kinematics. The fitness report covers 16 September 2004 to 10 January 2005.
A separate anonymous senior-chief account in the redacted Executive Summary identifies a fire-control background. Its extreme descent claims are not securely attributable to Day. The publisher of Underwood's 2019 interview explicitly corrected an earlier attribution of that anonymous source to him.
Evidence review
Day's duties explain his access to the operational picture. The distinction between a processed tactical display and the underlying returns matters: publicly described contacts, their association and their inferred motion cannot be independently reconstructed here without the source data and system settings.
The SCU interview-history discussion notes differences between an earlier online account and later statements, including claims about the object entering the water and the recording system. Its preference for the first 2018 interview is an investigator's methodological choice. A later account cannot be treated as evidence recorded during the November 2004 encounter simply because its witness had the relevant professional experience.
Statement and reporting history
16 September 2004–10 January 2005: period covered by the reproduced Princeton fitness report.
November 2004: Princeton operational setting described in later interviews.
2010: earlier online account discussed by SCU's interview-history appendix.
15 January 2018: first Powell interview identified in SCU's ledger.
March 2019: SCU publishes its retrospective investigation.

Scans of PDF pages 256–257 inspected for rank, speciality, ship and duties. The fitness report covers 16 September 2004 to 10 January 2005. These reproductions support professional-role attribution, not the measured performance of the unidentified contacts.

VFA-41 aircrew member associated with the later infrared recording
Chad Underwood
The later sensor encounter
In Matthew Phelan's edited December 2019 interview, Underwood says he concentrated on the sensor recording and did not make a naked-eye sighting. He describes unusual apparent target motion on instruments, while conceding that he cannot visually confirm the apparent acceleration at the clip's ending. The interview is a later, condensed account, not a transcript recorded in the cockpit during the encounter.
Fravor's 2023 testimony also names Chad as the person who took the video and attributes radar jamming to the later crew. That establishes Fravor's identification and interpretation of a different sortie; it is not Fravor's direct observation of Underwood's cockpit indications.
Evidence review
The redacted Executive Summary describes a later weapons-and-sensors operator, no direct visual acquisition, difficulty maintaining radar tracking and loss of the infrared target without a subsequent attempt to slew the camera. It does not name Underwood, and its precise crew-role assignment cannot be transferred to him solely from the shared recording narrative.
The later report says no characteristic jamming indications were observed, whereas Fravor's testimony describes deliberate interference. Failure to hold a track, electronic jamming and apparent image motion are distinct claims. Resolving that disagreement requires more than the released clip and the accounts examined here.

Comparing access without merging the evidence channels
Dietrich's testimony strengthens the first encounter's reported visual history; Day's concerns explain the shipboard decision to investigate; Underwood's recording adds a later sensor episode. None of those contributions alone demonstrates that every reported contact belonged to one continuously tracked object. Fravor's controller-reported reappearance at a distant patrol point is a further association claim, rather than a visually witnessed sixty-mile flight.
The public retrospective summary itself preserves differences across platforms. Its E-2 account describes a weak, intermittent return without an obtainable velocity, while the first F/A-18 section reports clean fire-control radar displays. These distinctions qualify a blanket assertion of continuous confirmation by every sensor. Operational accounts can agree that something unusual was investigated while differing on what each system detected.
The short CVW-11 reproduction and later interviews differ on visibility, distance, object size and the water disturbance. SCU regards the reproduction as usable because some details align with witnesses and ship records. Its further argument that agencies did not reject the document when sent with information requests is not affirmative authentication. The document remains useful for comparison without becoming a securely signed 2004 statement.
The released infrared sequence belongs to the later sortie. Its relationship to the earlier visual object rests on the operational narrative and source association, not on an inspected uninterrupted recording of both phases. The redacted report expressly says the later crew could not confirm that identity through a direct visual sighting.
The record supports a reported operational encounter with unequal access and a recoverable public recording. It does not supply the original ship-radar returns, the complete later aircraft radar record or a synchronised measurement set establishing all claimed trajectories. Those specific absences limit technical reconstruction; they do not remove the value of the participants' separate accounts.
