Some people are saying these are either UFOs or a foreign country. I believe that these HAVE to be domestic. Look – if China/Russia/etc can overfly our most sensitive military bases and our Air Force, etc. doesn’t respond, the USA has gotten PUNKED. What is actually happening is you are seeing some sanctioned activity either by a commercial contractor of the Federal government, or you are seeing some secret Air Force tech. The Army, etc will just deny, deny, deny, because they know in a couple of days this will fall out of the news cycle.
I’d be curious to hear people’s theories to see if I’m alone in my line of thinking or not.
If it was planes: then the FAA would be looking up whomever it is and slamming them in court and otherwise. Look at typical airspace violations – they pounce on the offenders extremely quickly and there are immediate consequences. There is an immense amount of radar coverage over the US and any “mystery plane” not flying with their ADS-B transponder can be met with a response up to and including fighter jets being scrambled.
Regarding drones, it’s pretty much a weekly occurrence that some numbnuts flies a drone in restricted airspace. The FAA have gotten very good at tracking down these folks.
So basically, both of your theories happen routinely and our government is very practiced at dealing with them.
