It’s a good thing the crew members of that UFO are aware of FAA regulations about having collision-avoidance lights turned ON around populated areas ...

The good aliens keep collision lights on.

I'll bet you a good steak dinner this is just someone's drone. So technically yes, it is an un-identified flying object, but only because the people making the video don't know what's going on. It almost certainly isn't actually aliens but far more likely to be human tech.

The Northrop Grumman X-47B and BAE Systems Taranis are both delta-wing triangles.

Heck the NG bird is being developed for the Navy, finding one flying around Naval units would not be surprising at all. Not telling every squid on every ship every thing that is going on, also not surprising. The BAE bird was merged with a Dassault program and they are still trying to develop and sell it. Wouldn't be surprising to have them putting it through it's paces as a demo.

Indeed drone manufactures obey FAA rules.
