To be clear, your friend and humble narrator does not wear a tinfoil hat, nor does this reporter believe the U.S. government is competent enough to keep proof of alien life secret from the American public. (Just remember, the same government that conspiracy theorists allege is keeping the truth about UFOs under wraps also runs the Defense Finance and Accounting Service.)
Yet a number of credible media outlets have reported that Navy pilots are increasingly reporting sightings of unidentified aircraft, and the service is taking them seriously for a change. Politico's Bryan Bender reported in April that the Navy was working on new guidelines for reporting such aircraft in the wake of increased sightings in military ranges and airspace.
Helene Cooper of the New York Times recently reported that Navy pilots saw a slew of unidentified aircraft in 2014 and 2015 while flying training missions off the East Coast. In fact, a pilot from Virginia Beach nearly collided with one of the unknown aircraft in late 2014.
The strange aircraft had no visible engine or infrared exhaust plumes, the New York Times reported. They could fly up to 30,000 feet and they were able to loiter in the area of U.S. warships for 12 hours at high speeds.
