There were no planes. Aluminium wing tips do not cut through structural steel I beans like a cookie cutter. You're talking about a building that was built with the I beams in the outside. In order for that to happen that means the planes wingtips would have had to cut through steel oriented with its edge pointing outward meaning that the plane tips would have had to cut through over a foot of structural steel in order to create the shape outlined in the videos. Absolute bullshit. If you watch this video you can see clearly that there is absolutely no plane and no sound of a plane either. https://vimeo.com/507772168
