That pretty much mirrors something a dear and wise friend had to say about
that footage. As she put it, the world should be reminded of the horror of
that day, and to remember that it's not just Manhattan or the US that's a
target, but anyone, anywhere.

That said, I'll just add this. While I agree that "it *is* an important day
in our history. And it *is* remarkable, unique aviation footage.", I think
you agree that the event depicted in those clips is far more emotionally and
historically significant than anything else on that page, and that bothers
me. It's just there, alphabetized along with airshow mishaps and such,
analogous to having the zapruder film on a page full of presidential parade
clips. I know it isn't your intention to cheapen 9/11, but as that page is,
that's the impression I get - another "cool" aviation video.

I'd suggest setting it apart from the others somehow. Not necessarily it's
own page, but just not lumped in with the rest as it is. But again, it's
just me thinking out loud here - you said you weighed adding them at all,
and I respect your right to operate your site as you see fit. Just a
thought.
