The Boy Who Cried UFO.

They are Starting The Old Swamp Gas and Venus Rising Excuses Again!! 

That's right, our commercial and military pilots can't tell the difference between between a light reflected off of clouds or an actual UFO!   Why do we spend so much money training people who can't tell the difference between a cloud or haze and why don't our Very Expensive Radar Work?

The Navy tracks UFO sightings. Scientists explain what's really going on.

 
Sure, a Scientist who has never been in a fighter jet or manned the combat and control radar of our fighting machines is going to say, You're All Mistaken, it's Clouds or Swamp Gas or a Full Moon! 

(Tribune News Service) — The Navy caused a bit of a sensation this spring when it implemented a formal process for pilots to report unexplained aerial phenomena – what most people call UFOs – after being accused in the past of not taking such reports seriously.


Alas for those who might be tempted to make the leap, such sightings are not evidence of life on other planets.

No one doubts that the pilots are seeing something, but psychologists and specialists in aviation medicine say there are plenty of reasonable explanations for such sightings other than extraterrestrial beings.

Earthly sources of light reflected by clouds or haze, for example, or optical illusions wrought by fatigue after staring through a cockpit window for hours on end.

Another possibility is that the pilots were seeing some sort of experimental drone or other advanced technology about which they had not been briefed.
Or, the objects were simply satellites, such as those launched in May by the Elon Musk-founded company SpaceX, which prompted a flurry of UFO reports from puzzled observers, the news agency AFP reported.

OK, the SpaceX craft looked like a Tic-Tac and submerged it's self under the ocean and then Zoomed at Ultra High Speeds Out Of Our Atmosphere in less than a Second! 
This is a long article in the Stars & Stripes and I think it is worth reading, this Female Scientist and others gives all kinds of reasons the pilots aren't seeing what they are reporting.
YES, it sounds like a coverup.
