This comment reminds me of a quote attributed to Admiral William (?)Halsey (or at least spoken by James Cagney as Halsey in the movie "The Gallant Hours"
"There are no great men. There are only ordinary men forced by circumstance to become great."
While we honor our proven heroes, we must not underestimate ourselves. If called upon, we will give our best; if necessary, our all. Keep faith and trust God to give every grace needed at any moment.
Just think, if we live right, one day we'll meet the heroes of September 11 face to face.
