As the UFO mystery deepens, scientists must engage with the data

In 2014 and 2015, for example, at least 50 to 60 naval aviators training in tightly controlled airspace off the U.S. East Coast observed unknown objects exhibiting extraordinary flight characteristics. Critically, aircrews observed the mysterious craft visually or via sensors on a daily basis. Pentagon officials ruled out secret U.S. technology, leading some analysts to surmise that the mysterious objects were foreign surveillance platforms. But recent reporting appears to undercut this theory.
