An alleged UFO sighting roused Washington area motorists into a frenzy Wednesday night after numerous drivers reported seeing a saucer-shaped aircraft on the Beltway and I-270 in Maryland.

The reports began appearing on Twitter late Wednesday night, with users speculating that the apparent unidentified flying object, which was being towed behind a tractor trailer, was a sign that “aliens are real.”

But, as it turned out, the alleged extraterrestrial vessel was just a large military plane.

According to Maryland State Police, the plane — which reportedly measures about 82 feet long, 32 feet wide and 14 feet high — was being transported to the Naval Air Station Patuxent River in southern Maryland.
