If it is true which it looks that way they will use the planes for a bigger bang then in 911. They can put a dirty bomb inside one or a nuclear bomb to use as an EMP. Have the planes flight in all the zones needed and use them to create an EMP on the U. S. to take the grid down.
They would not need to go inside the U. S. just around the coasts 50 to 100 miles away would do it. The center of the U. S. would still be alive but what a bang it would do. Just think out loud.
