During 'Fall Out,' at one point the President is attracted to the red 1 rocket by a piercing sound, which is quite alarming. More than that, the steel eye in the hull of the rocket emits a green light, and the President stares into the eye..
"Yes of course.........naturally it would expedite matters....very well."
The President is getting his instructions, telepathically from Number 1, and give the impression that it is done so telepathically. After all the President isn't on the telephone to Number 1, nor do we as the viewer hear Number 1's voice, but the President clearly does in his head, and so must be susceptible to telepathy!
Be seeing you
