No he wasn't. And even if he was, NOBODY could have possibility tied Bin Laden to 9/11 IMMEDIATELY after hearing an airplane flew into a building in New York.
If you believe that no one could have linked Osama Bin Laden to 9/11/01 immediately after the plane crashes, you will be shocked and amazed to read this live FR thread from 9/11/01:

Osama Bin Laden is mentioned shortly after the second plane crashes, just a little after 6:00 a.m. These threads (and there are more) were happening in real time on that day. If you haven’t seen them, enjoy! (Not sure that is the proper word, but they’re pretty enlightening and interesting.)
Well, I did.
