I’m guessing maybe all this weird airplane stuff is a test for some future op.
Perhaps to keep real POTUS secure.
Perhaps to fake an incoming nuke.
Perhaps multiple uses.
So many possibilities.
The Boeing Honeywell Uninterruptible Autopilot (BHAUP) gives full control of an aircraft to external entities. All modern commercial airliners built in the last decade have been so equipped. Planes so equipped can take pilots “out of the loop.”
MH370 was commandeered via BHUAP.
