I wonder if this was a cyber attack—somehow terrorists were able to turn things off and change direction from the ground. Re-program the flight path —have the ship fly up—deprive the plane of Oxegen and kill the crew and passengers and set it to fly til it ran out of gas and crashed. There may have been something in the plane that helped this out—in baggage. If this is true—look to see more planes go missing in the future.
The big advantage to that, would be you could fly a commercial passenger plane into a designated target. (Like the White House, the Pentagon, Disney world, a Nuclear Power plant etc.)-Tom
Remember the newspaper writer in the Mercedes in Los Angeles. Soon after there was the brilliant hacker who was able to program ATMs remotely and interfere with pace makers. Somehow I thought it was our guys who wiped them out. Maybe not.
