The spotting took place around 11:00 p.m. Wednesday when drivers first saw the craft being hauled on a flatbed truck on I-270, and then again down I-495.
An official at Northrop Grumman confirmed to FOX 5 on Thursday that the craft was actually an X-47B Unmanned Combat Air System.
They say the unmanned drone
was being transported from Edwards Air Force Base in California to the Naval Air Station Patuxent River in Maryland for testing.It wasn't the first time this style of aircraft had had been mistaken for a 'UFO' while being transported. Last year, residents of Cowley County, Kansas made a similar mistake. . . .
