美国有线新闻 CNN 五角大楼正式发布3段UFO影片

（单词翻译）

Which of these stories made headlines in 1947? Flying Saucers Seen in Washington, Communism Declared in China, Barbie Doll Makes Debut¹, or First Corvette Introduced? A civilian² pilot named Kenneth Arnold said he saw flying objects that a reporter mistakenly called flying saucers.

For decades, the U.S. military has been studying aerial encounters with unknown objects, aka UFOs. This week the Pentagon released three videos that were recorded during U.S. Navy training flights and they apparently³ show mysterious airborne objects captured by the planes infrared⁴ cameras.

One of the recordings⁵ was made in 2004. A pilot who saw that object said it moved rapidly in ways he couldn't explain. The other two clips were captured in 2015 and in one of those a pilot can be heard saying the object is a drone. So was it? The Pentagon says whatever was recorded remains⁶ unidentified and it didn't give any hints as to what it thinks the objects might have been.

The reason the military officially released the videos yesterday after they had been published without permission by other organizations, was to help clear up public debate over whether the videos were real and if there's any more to them. The military also wants to encourage pilots to report anything strange they see because any unauthorized object in the sky can be dangerous to aviators⁷ and U.S. military operations.
