Bombs Going Off Before 2nd Hit

Even though this video (screen capture above) doesn't show the 2nd plane and you can't even see the point of origin of the south tower fireball, the video still shows a number of fascinating details.

Jane Doe/Judy Wood has annotated a number of these events here, but the bottom line is that it appears that explosives or at minimum incendiaries are going off in both towers JUST before the 2nd hit.

This evidence, coupled with the amply documented evidence of firemen hearing bombs going off in the towers before they collapsed, suggests that the towers were indeed laced with explosives that progressively weakened the structures, and that likely helped the eventual collapse occur-- even though I think it is quite likely that the driving force of the global collapses was some sort of exotic high-tech weaponry.
