The re-creation of what probably occurred during Flight 93, as seen on the Discovery channel last night, was a compelling look into what must have been a 'beyond terrifying' experience.
The most interesting fact that emerged for me - as stated by the wife of one passenger - was that the passengers who attacked the terrorists in the cockpit did not necessarily do so as a heroic attempt to prevent the suicide bombers from crashing another plane into a another building.
The fact that the plane crashed, and that they were unable to gain control of it as they hoped they could, has been marketed by the media as their attempt to prevent the Capitol Building or White House from being struck.
Yes, thankfully, that was a result of their amazing courage; and they did save countless lives by not allowing the plane to reach Washington. But it was probably not their main intent.
I think they hoped to grab the controls and land the plane safely. It is said that one of the passengers was a pilot.
Here is a photo of a memorial rock that has been placed at the crash site. 
A more extensive Flight 93 Memorial has yet to be created, but donations are being sought now. Google "Flight 93 Memorial" if you'd like to know how you can contribute.
They were courageous heroes; but I believe they wanted to see their loved ones again, tuck their children into bed at night, and continue to live and contribute to society.
Ordinary people... who made an extraordinary attempt to survive.
Roll on!
