Have you forgotten that TODAY (9-12) is ALSO a historic American/USA anniversary?

This date (in 2001) was, for the very first (and only) time in USA aviation history, one where NO non-military aircraft were legally permitted to take-off.

My question did not deal with the actual historical fact I mentioned; it dealt with whether or not you were able to remember that fact, so I have not authored a question to which I already knew the answer, as I don’t know about any member’s ability to recall certain factual items of information.

So there.
