Motorists travelling along Washington D.C.'s beltway photographed a shrink-wrapped government military drone being transported on the trailer of a semi-truck, causing many to mistake it for a UFO:

Some folks in the Washington, D.C., area are buzzing about what they thought was a UFO atop a flatbed truck on the Capitol Beltway.

Turns out the disc-shaped object was just a run-of-the-mill military drone.

MyFoxDC reports that what drivers saw—and some photographed—around 11 p.m. Wednesday on Interstate 270, and then later on Interstate 495, was an X-47B Unmanned Combat Air System being transported from Edwards Air Force Base in California to the Naval Air Station Patuxent River in Maryland for testing.

During its travels through the D.C. area, local station WTOP reported a flurry of activity on Twitter about the strange-looking object.

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, the Daily Caller reported.
