I found it to be an interesting tidbit of information that I didn't know (and I assume most people didn't know as well).
I had largely assumed that fighter jets were delayed from being scrambled, etc. because no one really knew the planes were hijacked at such an early stage.
Yeah, I found it interesting that fighters were scrambled, they just couldn't find the plane on time.
Although the truth is the jets probably wouldn't have stopped the attack even if they found AA11, no one dreamed they would crash it into a building so they wouldn't have shot it down....
