Literally was just watching videos about this a few minutes ago. I was pretty young when 9/11 happened. I obviously remember flight 93 and the lack of evidence of a plane crash and most of that stuff. But it was the first time I had seen the interviews of the eyewitness accounts from that day. So I'm just hearing about how they saw a second plane. What do people think happened? The second plane's description sounded like an unmanned drone.
