No there were lots and lots of heroes that day. Too many to try to go back in news and find them all. I recall one man who stayed with a coworker who was in a wheelchair and unable to leave the building. How about all the first responders who surely knew entering the building to try to help others was a suicide mission at best?
See, I disagree. These were people just doing their job. They had been trained to run into burning buildings. They just didn't expect these burning buildings to collapse. You can be quite sure that after the first tower fell, no one climbed up any stairs in the other tower while it still stood.
