Here's an email I received today... the emailer left me with full contact information but I like to keep these things anonymous.
I was on a flight on a American Airlines flight on 9-11 from Cleveland to Denver via Chicago. We left at 9 am I believe. We were in the air a short time and the pilot came on and said, "there is a national emergency and we have been told to land immediately at the nearest airport. We do not know the details but we should learn when we land". The nearest airport was Toledo which we just passed so we dropped down out of the sky, landed and rolled along the runway then parked next to another plane that just landed. We were asked to walk off of the plane and go into the terminal building. It wasn't very large just a few gates.
Soon after I saw an F-16, yes I know what they look like, take off from nearly the same runway as we had landed. After that we were told by a cop to go downstairs to the ticketing area. There was a big TV on that everyone was transfixed on. One of the towers was burning. No one knew what was going on but soon after, we witnessed live, the second plane hit the WTC. I don't know the timing of these events, but the single F-16 I saw take off left well before the second plane hit the WTC. Someone said they were just National Guard and would not be involved in anything important. But your web site makes me wonder. I later drove near where the plane crashed in Pennsylvania last October and I remember people saying that there were pieces of it far from the crash site, but I never realized the implications of this.
