How to take 75 of the best missile/nuke engineers off the board for paper clip 2.0?
This is how. Delay the flight. Kidnap all the Passengers. Send a remote controlled airplane up (tower can't talk to it), shoot it down, sanitize the crash site, admit to shooting it down and move on down the road.
Now you have your engineers and the world thinks they're dead.
That's how these psychopaths have been doing things for centuries.
Look at the Titanic.
