"A saucer-shaped object on a very wide flatbed truck had some people wondering if the government was moving a UFO in or near Washington, D.C., Wednesday night..."When motorists snapped photos of the strange object and posted them on Twitter, some people became concerned enough to call local police."
It was actually a military drone.
[Pet peeve: UFO stands for Unidentified Flying Object. It's not (necessarily) an alien spacecraft. Even if this was one, it couldn't be a UFO because it wasn't flying!]
The picture at right looks like New Orleans after Hurricane Katrina, but it was Elkridge, Maryland 40 years ago, after Hurricane Agnes.
