AIR 20/7390 — Air Staff / Intelligence Files on Aircraft and UFO Sightings
A UK Air Staff / Air Intelligence file mixing aircraft incidents and UAP sightings, showing how the MoD framed unexplained aerial objects as an air-defence intelligence problem before the modern Sec(AS) UFO desk existed.
Brief
AIR 20/7390 is a pre-2008 deposit at The National Archives produced by the UK Air Staff / Air Intelligence directorate. It combines conventional aircraft incident records with UAP sighting reports, illustrating the institutional framing that treated the phenomenon as an air-defence intelligence question rather than a standalone research category. The file predates the dedicated Sec(AS) UFO desk, placing it in an earlier administrative era when no specialist office existed. All 21 pages are image-only scans; no body text was extractable by the ingest process.

Key points
- The file mixes conventional aircraft incident records with UAP sighting reports under a single Air Intelligence reference, reflecting MoD's air-defence-first framing of unexplained aerial objects.
- The deposit predates the modern Sec(AS) UFO desk, placing the administrative provenance in an earlier UK intelligence era with no dedicated UAP office.
- The file was deposited at The National Archives before 2008 and released on 2008-10-08, making it part of the wave of MoD UAP record transfers that accompanied the closure of the UK UFO programme.
- All 21 pages yielded only catalogue-reference watermarks on extraction; the substantive content is encoded in images and is not machine-readable from this ingest.
Most interesting
- The file's catalogue structure — grouping aircraft incidents alongside UAP sightings — is itself evidence of the MoD's working assumption that UAP belonged inside the air-defence taxonomy, not outside it.
- The Sec(AS) UFO desk, referenced as a later development, was eventually stood up within the Secretariat (Air Staff) branch and became the public-facing intake point for UK UAP reports until its closure in 2009.
- The 2008 batch release to The National Archives was one of the largest single transfers of MoD UAP records and covered files spanning several decades of Air Intelligence activity.
- The four distinct image references across 21 pages suggest the file is a composite of multiple original documents bound together under one catalogue number — a common archival practice for thematic intelligence folders.
