The alleged UFO seen on the Washington, D.C. Beltway on Wednesday night was actually a military drone on the top of a flatbed truck, according to reports.
Many drivers saw it - and some photographed it, against the hands-free law - around 11 p.m. on I-270 and I-495, on the perimeter of the U.S. capital.
Alas, the UFO was really an X-47B Unmanned Combat Air System being transported from Edwards Air Force Base in California for military testing.
It was en route to the Naval Air Station Patuxent River in Maryland.
During its travels through the D.C. area, local station WTOP reported a flurry of activity on Twitter about the strange-looking, UFO-like object.
Given how foreign that thing looks compared to most people's conventional idea of what airplanes look like, the hullabaloo is somewhat understandable.
Just imagine if those things cruised around during broad daylight!
This not the first time a drone was mistaken for something alien.
Last year, a drone being transported by flatbed to Pax River for practicing aircraft carrier takeoffs and landings was also mistaken for a UFO.
