Boy, would I have loved to have seen that. Their own psychotic jihad mindset almost got them killed before they achieved their objective. Freaks.
Of course, if it HAD broken up in the air just before hitting the south tower, FR would have been overrun by "the US government did it"/"TWA 800! TWA 800!" conspiracy theories, so maybe it's better that it happened the way it did. (Factoring out the human deaths, of course.)
