Secret Plane in Area 51
This is a photo of a freakily futuristic plane that was built by the US government. Back in the 1950s, this super-secret stealth plane was making its rounds near Area 51. Some people have speculated that this is what citizens were seeing when they reported UFOs in the area. Of course, this was a top-secret operation back then, so the US government had to keep mum about the situation. It's still unclear as to why these planes were in use, though.
