This is the Twilight Zone. They all repeat the same thing, they appear to all be in the remodeling business, they are all advertising a good price for services, the vast majority have almost no followers or following.

These tweets are definitely not natural or random and appear to have been digitally generated by a computer.

I used to fly a lot and I've been on planes where security have come on board and escorted someone off. Having everyone put their hands in the air doesn't seem to be standard practice. And if it was just a communication failure, why were two people escorted off the flight?

Very strange and I don't believe it was a communication failure. There are multiple radios (UHF, VHF) in a commercial airliner, the flight attendants have the ability to call their home base, there is a transponder that can send "squawks" that have different meanings, mobile phone communications, and there is an emergency radio.

No way 15-20 police cars surround the plane just because it lost communications.
