The CARET image is back — now as an alleged Yankee Blue briefing slide
A 2007 image from the anonymous CARET document package is circulating again after Steven Greenstreet said he saw it in a Yankee Blue briefing. The public evidence establishes the image's online history, not the briefing claim.
A green, mechanical object with three padded arms has returned to the UAP conversation. It first became familiar online in 2007, inside an anonymous packet of documents that claimed to describe recovered extraterrestrial technology. On July 21, Steven Greenstreet posted the image again and wrote that it was one of the “alien” images in a top-secret Yankee Blue USAP briefing document he had seen.
The image has a public history. The briefing claim does not yet have a public document behind it.
The object is the CARET “A1” image
The image is Figure 4.1 in the Q4-86 Research Report, a document attributed to the alleged Palo Alto CARET Laboratory. The report calls the object “A1” and describes it as a small “personal antigravity generator.” It is part of the larger CARET package distributed online in June 2007 by an anonymous source using the name Isaac.
The report is not a government release. It is an anonymous, web-circulated document claiming to be a scan of an internal 1986 research report. No named author, originating office, document-control trail, physical original, or official authentication accompanies the public copy.
Why Yankee Blue changes the framing
Yankee Blue entered public reporting in 2025 through accounts of an Air Force initiation practice: personnel entering highly classified work were shown supposed alien-technology material and told they were being read into a secret reverse-engineering effort. The Wall Street Journal reported that AARO investigators concluded the exercise was a long-running hazing ritual and that the practice was ordered stopped in 2023.
No AARO, Defense Department, Air Force, or independent journalistic response to Greenstreet’s July 21 post was located while this note was prepared. That leaves the earlier Wall Street Journal account as context for Yankee Blue, not confirmation of the image claim.
That reported pattern makes Greenstreet’s post interesting for a narrower reason than the post suggests. A public image from an old UFO-document package has now been placed inside the visual world of an alleged Yankee Blue briefing. The two stories already share the same vocabulary: classified access, anti-gravity hardware, and a document meant to be remembered rather than independently checked.
But similarity is not a chain of custody. Greenstreet did not post a page from the alleged briefing, identify when he saw it, or provide a second witness. The post itself offers no sourcing for the claimed viewing. This note assesses that attached evidence, rather than trying to infer a conclusion from Greenstreet’s wider UAP coverage. The public record establishes that the A1 image was online in the CARET material. It does not establish that Yankee Blue used it.
A closed loop is possible
If the image did appear in such a briefing, one plausible reading is not that the CARET report has been authenticated. It is that a publicly circulating UFO image became useful briefing material: an object with enough mechanical detail to look like evidence at a glance and enough missing provenance to resist a quick check.
There is another possibility: the image may be remembered, described, or reposted without having been in the briefing at all. Neither possibility can be resolved from the post alone.
The next useful item would be simple: a contemporaneous briefing page, a date and unit, or an independent participant who can describe the same image. Until then, this is a story about an image’s second life — not confirmation of either CARET or Yankee Blue.
