In a move that has both civil libertarians and budget hawks nodding in grim agreement, the Trump administration has officially axed the Transportation Security Administration’s (TSA) “Quiet Skies” program—a covert surveillance initiative that, for over a decade, monitored American travelers without their knowledge (see, I bet you have never heard of it before).

Launched in 2010, Quiet Skies aimed to identify potential security threats by having undercover air marshals observe passengers exhibiting behaviors deemed suspicious. These behaviors included fidgeting, sweating, or using electronic devices in a certain manner.

The program cost taxpayers approximately $200 million annually but failed to prevent a single terrorist attack during its operation.

How it Worked

Under the now-defunct Quiet Skies program, you didn’t have to be a terrorist—or even under investigation—to find yourself tailed by a federal air marshal at 30,000 feet. All it took was brushing shoulders with the wrong person. If you traveled with, emailed, called, or were even loosely affiliated with someone flagged as a known or suspected terrorist, that was enough to trigger enhanced surveillance. No warrant, no charges, no notice. Just a quiet decision behind a government desk that you needed watching.

Once flagged, air marshals would shadow you on your flights, domestic or international, taking notes on everything from your behavior to your travel habits—how you boarded, how much you fidgeted, what you did mid-flight, and whether you looked nervously out the window. Keep in mind, this wasn’t based on concrete evidence or active investigations. It wasn’t even based on a reasonable suspicion of wrongdoing.

The criteria included things like travel to certain countries, shared phone numbers, facial recognition hits, or other vague biographical data. Once you were in the system, you stayed there for up to 90 days or three trips. One high-profile example? William Shaheen, husband of Senator Jeanne Shaheen, was swept up in the net after flying with someone the government deemed sketchy—three times. He wasn’t under suspicion himself, but guilt by association was the name of the game. That’s the twisted brilliance of Quiet Skies: it turned proximity into a liability and stripped due process down to the studs.
