If anyone knows the video I am talking about and has a link to it, I would really appreciate seeing it again.Sorry to be so vague, I wish I could remember more details.
Was it this one with Enya

This may not be the video you are thinking of, but this one shows the planes hitting the towers and people jumping.
It brings it all back for me.
I lost two friends on Flight 93 and one friend, a firefighter at the Trade Center.
