Late Wednesday evening, some drivers on the Beltway near College Park peered out their windows and saw something odd: An oddly shaped flying machine being hauled down the highway on a flatbed truck.

A couple of tweets later, people started to freak the hell out and the hashtag “#beltwayufo” surged atop the trending topics. Seriously, just conduct the search yourself. This was too ridiculous to merit a Storify module at midnight.

Obviously, this was not an alien spacecraft. (And frankly, considering the last two movies about alien species—The Avengers and Prometheus—both involve a lot of human misery, that’s kind of a big relief.) It was something perhaps even scarier: an unmanned military drone.

The aircraft, a U.S. Navy X-46B, was being transported from West Virginia to the Patuxent River Naval Air Station in southern Maryland, WTOP reported last night.

Manufactured by Boeing, the X-46 was an experimental model partially funded by the Defense Advance Research Projects Agency first rolled out in 2000. But it was quickly deemed redundant when Northrop Grumman introduced the X-47 in 2003.

So calm down, enjoy your day and remember, you did not see a UFO last night.

Editor’s note: Seriously, it wasn’t a UFO. Just like this editor’s note was not ordered by the spooks at DARPA.
