I wish someone had done a video. Sad to see a tower come down, but the sort of thing most of us will... hopefully... never see in person.
Was that a demolition company doing the collapse of the towers? It looks like they are going to cut the highest guy first, which is usually wrong. Every crew I have worked with starts with the lowest guy, which will cause the tower to collapse under the pull of the higher guys. Cutting the top guy first will create an uncontrollable collapse since the top section can fall unpredictably on the lower guys.
