Oh wait. But I DO understand how documentaries are made.
Later in the afternoon, Gedeon just happens to be focusing his Sony on WTC7. POOF! Amazing indeed. That's how documentaries are made!
You have two guys filming a supposed documentary about a probie fireman that happen to be embedded in the nearest firehouse north of the WTC complex. Their goal, as stated, was to film the probie fighting his first fire. Long wait, it turns out, because they never get THAT footage. On the morning of 9/11 Jules goes out with 16 firemen to investigate an 'odor of gas' call. The probie doesn't go, he gets to watch the firehouse. Oh well, Jules needs the practice (his words). When he arrives on the scene he lines up the north tower perfectly dead center and remains on his mark for a time. No traffic, no interference, no firemen talking to him, he just waits. Plane noise, he swings his camera perfectly and already has the north tower centered. BULLSEYE! Gedeon is on another street catching people wheeling around and looking up. His camera was also ready. Nearly 3 seconds of 'man, they're going to love it when I pull this shot out!'.
Then Jules rides with Pfeifer to the north tower. Takes less than five minutes - closer to two. Asks Pfeifer if he can enter a potentially dangerous situation, and Pfeifer doesn't hesitate and invites Spielburg, errr Jules inside.
All told? You have two guys when the day is over, that capture the first strike, a reaction to the first strike, the second strike, both twin tower collapses, the only admitted film from inside the north tower, AND the collapse of WTC7. Not only do THEY survive, but everyone from Duane St. survives. They hug at the end, and all is well.
So cool. But PLEASE watch the movie. They give it away several times leading up to the morning of 9/11. They knew in advance. Pure and simple. They followed a script and had foreknowledge of what would happen, where, and when. No rocket science here, folks. You can see it for yourselves.
