Those videos were FLIR, not radar. These are trained pilots with experience in identifying flying objects, and the thing that stood out to them is they didn't see a source of propulsion. The movement characteristics were unlike anything they've seen. The object in question was flagged for their inspection by radar and they followed up visually. What they saw was baffling. The videos came from the aircraft and have been released by the Pentagon.

Regarding how many eyes have seen this. Take a read of the Nimitz Carrier Strike Group report of the incident (PDF) which might answer some of your questions and raise others: https://media.lasvegasnow.com/nxsglobal/lasvegasnow/document...

Edit: adding a couple of excerpts from the report.

- "AAVs would descend "very rapidly" from approximately 60,000 feet down to approximately 50 feet in a matter of seconds. They would then hover or stay stationary on the radar for a short time and depart at high velocities and turn rates"

- "The AAV did take evasive actions upon intercept by the F/A-18 demonstrating an advanced acceleration (G), aerodynamic, and propulsion capability."

- "The Anomalous Aerial Vehicle (AAV) was no known aircraft or air vehicle currently in the inventory of the United States or any foreign nation."

- "The AAV exhibited advanced aerodynamic performance with no visible control surfaces and no visible means to generate lift."

So here's what this comes down to. Three possibilities in order of likelihood:

* A: Psyop fakery: doctored videos were released through official channels, trying to fool other countries we saw something unusual. But why? Who benefits from that? What does it show to others, that our own military is unaware of experimental technology?

* B: Another country has made a giant leap in technology, possibly physics resulting in aerial combat superiority and this should scare any military leader, because if it's real this means the U.S. is no longer the biggest sky predator.

* C: Nonterrestrial origin.

I don't think there are any other possibilities. Last two are a game changer. First one is just bizarre. The weirdest thing, again, is that these videos were released by the Pentagon. You can request copies yourself by filing a FOIA request with the following wording "seeking cockpit videos cleared for release to Louis Elizondo in the fall (September-October) of 2017."
