I tend to agree somewhat. First attempt in '93 failed. Somebody went back and did their homework, and this time were successful.
I am still a bit unclear as to exactly where the first plane struck tower #1. Dead center, (side to side, that is, not top to bottom), or approximately centered between the core and one side, as the second plane seemed to. Second plane appears to have gone in one side and sheared its way through to the point of almost (or perhaps succeeding in) coming out the other. Conflagration ensues, weakening the structure over time to the point of collapse of that floor. All floors above come down, floors below cannot accomodate this sudden weight crashing down from above, and they all pancake down to the ground.
One tower collapsing, perhaps luck plays a role in bringing the whole thing down. Two towers collapsing, damn good luck, or, as I am more inclined to believe, somebody had to have a darn good idea how to make it happen.
And when I refer to luck above, I am strictly referring to the luck running with the maniacal cowards, to accomplish their objective, not to be construed that I was hoping this would happen.
When I was doing research for our terrorism response plan, one of the things I found out was that the bomb in the last World Trade Center bombing was actually strong enough to bring the building down, and the planners had it figured out fairly well. The problem was that the people who carried out the bombing put the vehicle in the wrong place.
The original plan was to take out the base of one corner of the "cube" that provided the infrastructure support. If the bomb had been parked in the right place, it would have collapsed one tower into the other.
I suspect that the reason the WTC has been targeted multiple times is because the terrorists believed the nature of the structure would allow a complete collapse under the right circumstances.

Also, late last night and this morning, Fox News showed some footage they got from a crew in the area that did film/video the first impact. It was similar to the second, only higher. It's really hard to tell from the video they shot, but it looked like that plane had to come in higher because of other buildings in the area. I think the second plane had a more open approach, so it could hit lower.
