The patrols originate from several bases of which Minot is but one; there are also certain explicit protocols in place that, in exceptional circumstances, do permit a nuclear launch in the absence of presidential authority and in any event the President is actually positioned to give the green light 7x24x365 since the nuclear football (the briefcase with the verification and launch codes, which are changed daily) is literally handcuffed to and carried by a military attaché who is assigned to the President on a full time basis. That individual is probably never more than a few paces from the President at any time, night or day, goes where he goes, and travels where he travels.
Yes I'm aware of all that, however the statement was made that each one of these flights already had the "green light" when they took off, I don't believe that to be true.
