You should check the interviews (there are several, including a 60 minutes) with the pilot David Fravor (1).
There are two pilots and two wizards that saw the same with their own eyes (even I have only see the other pilot confirming it). That's an UFO. That doesn't mean that it's extraterrestrial.
To say that it's extraterrestrial at this point, is, in my opinion, so ridiculous like to say that there is nothing to explain (like the author of the article seems to believe).
