I remember the gif of that being on here before but its not real but idk maybe it is i missed both impacts live 
I remember typing a paper that was due later in the day, someone running into the lab to say something hit a building in nyc and theres a tv in the art room with cnn, i finished half and went to see. It seemed like it wasnt burning too bad and that it was going to either go out or be put out easy. So i went back to type the rest. 
Then someone else ran in and said that a second had hit and that everyone was now calling it all a terrorist attack or something. 
We ended up watching alot of it but i cant remember if i saw it fall down or not live
We did bring up bin laden almost immediately in a discussion about it all
Internet was still up but it was super super slow overall. Retrospectively nsa was probably running ALL in/out usa server traffic through their scanners set to high. 
Anyways it was a silvery blurry gif i remember seeing but it went through the building without being destroyed but burnt it around it

yes this seems to ring some bells. 

esp the part about it going through. it kinda seems familiar.
