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.
With summer 2025 in the rearview mirror, we’re taking a look back to see how federal actions impacted heat preparedness and response on the ground, what’s still changing, and what the road ahead looks like for heat resilience.
Satellite imagery of RAF Lakenheath reveals new construction of a security perimeter around ten protective aircraft shelters in the designated nuclear area, the latest measure in a series of upgrades as the base prepares for the ability to store U.S. nuclear weapons.
It will take consistent leadership and action to navigate the complex dangers in the region and to avoid what many analysts considered to be an increasingly possible outcome, a nuclear conflict in East Asia.
Getting into a shutdown is the easy part, getting out is much harder. Both sides will be looking to pin responsibility on each other, and the court of public opinion will have a major role to play as to who has the most leverage for getting us out.
