Discussion of the NOTAM for the area getting heavy discussion....in the comments at the Air Vent ...see link just above...#175.
There is some excellent analysis and commentary at that link but this is probably the most bottom line statement of all.
"How do I emphasize this enough, NORAD can track a baseball in orbit. They would not miss a major launch and for the pentagon to pretend that they might not know if it were a plane or a rocket, is a LIE."
