When Secrecy News gained unauthorized access to a restricted U.S. Army manual on visual identification of U.S. and foreign aircraft, we supposed that it was just one more case of unnecessary and inappropriate secrecy.
But it turns out to be something worse than that, since the document (pdf) contains a surprising number of technical errors.
The dimensions given in the Army manual for the Predator unmanned aerial vehicle are wrong, the Entropic Memes blog astutely noted. And the entry for the B-52, among others, is likewise incorrect.
“Please,” Entropic Memes exclaimed. “If they can’t get the details of one of their own systems correct, how much faith can you have that they got the details of anyone else’s systems right?”
In this case, the secrecy of the Army manual was not just an arbitrary barrier to public access. It also “protected” numerous errors that may make the document worse than useless.
Conversely, exposing the document to public scrutiny may now make it possible to correct its errors so as to fulfill its intended purpose.
Since it was posted on the Federation of American Scientists website 48 hours ago, the Visual Aircraft Recognition manual has been downloaded over seventy thousand times, an exceptionally high rate of access.
Update: “This is not a subject I’ve so far spent a lot of time on, but the entry for every aircraft I’ve looked up in the manual thus far contains errors,” adds Entropic Memes in a new post.
Over the past few months, the Trump administration has been laying the foundation to expand the use of the Defense Production Act (DPA) for energy infrastructure and supply chains.
Get it right, and pooled hiring becomes a model for how the federal government decides what to do together and what to do apart. That’s a bigger prize than faster hiring. It’s a more functional government.
As of March 2026, there were at least nine documented U.S. wrongful arrests tied to face recognition misidentification. Errors like these are as much human as machine.
No one will be surprised if we end up with a continuing resolution to push our shutdown deadline out past the midterms, so the real question is what else will they get done this summer?
