Yes there are literally thousands of videos from all angles. All of the major networks shot their own live footage from both helicopters and crews on the ground. It is one of the best documented tragedies in history.
I haven't yet seen footage of the first plane hitting but the second plane was captured by most networks. Update: I just did a search and found a few dozen videos of the first plane hitting.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
