In October 2023, a U.S. military aircraft during Operation T launched from Larissa Air Base, Greece, operating over the eastern Mediterranean region recorded an unidentified object its crew could not explain.
The encounter is documented in an official USCENTCOM mission report, declassified and released through AARO — the Pentagon's UAP office.
The report confirms the crew observed lx poss uap (see uap 1). But the specifics — position, sensors, identities — are withheld under national-security and privacy exemptions.
Below is the document itself, reconstructed with the redactions preserved, followed by the full narration transcript and the approximate location of the encounter.

Where It Happened
Full Transcript
At 00:35 Zulu, an aircrew that launched out of Greece logged something they couldn't explain: a possible UAP, noted simply as 'UAP 1.'
It was October 2023. They'd taken off from Larissa Air Base just after 23:39, checked in with an asset, and were collecting full-motion video and signals intelligence when they saw it.
The declassified mission report is here — but it's a maze of black bars. Nearly every operational detail is hidden under national security, and even the crew's own observations are partially blotted out.
What exactly did they see? What did their sensors capture? The redactions swallow the specifics, leaving only the bare notation: 'observed 1x possible UAP.' No shape, no speed, no explanation.
