Harry Reid was U.S. Senator of Nevada, where Area 51 is located. He was one of the most powerful people in Washington D.C. as Senate Majority leader for a decade and a member of the Senate Intelligence Committee. He was in the best position to know everything about UFOs, captured alien craft, and reverse-engineering alien technology. Here is his statement on Twitter:

"I’m glad the Pentagon is finally releasing this footage, but it only scratches the surface of research and materials available. The U.S. needs to take a serious, scientific look at this and any potential national security implications. The American people deserve to be informed."
