[Die Hard 2: Die Harder] Ok, so let's say everything works and we take off with the general in our escape 747...then what?

It's a 747!  It isn't stealth and it isn't fast.  It's a long way from Dulles Airport to Cuba or Val Verde or wherever the hell we're supposed to find sancutary.    I wouldn't dare say this in front of Col Stuart, but I'm having serious doubts about the efficacy of this plan.  We already just kinda lucked out on the weather.

One of the reasons why they had to hijack the Air Traffic Control was precisely to resolve this issue. By cutting that ATC off from the rest of the grid, they could put in a flight record on their own 747 to claim it's a... say, domestic flight out of Dulles airport and flying to Cuba.

By the time the alarm is finally raised, the mercenaries were hoping to have flown out of range for the US army to do anything about it.
