Here are a few posts sent in by our readers over the years, as we come to the 15th anniversary of September 11th.
1. 'I was offered a job with a new company, based on the 101st floor of 1 World Trade Center. I decided to stay put, but encouraged Pam, a good friend of mine, to accept the position instead.
She got promoted, had her own office....and lost her life on 9/11. I'm sorry for pushing her to take that job. Pam will be missed for the rest of my life. R.I.P my good friend'.
2. 'The memory of the people jumping from those buildings will never leave me. How I hope we never see its like again'.
3. 'The level of kindness, respect and calm I experienced when boarding a random bus to get to 22nd Street was so inspiring. We were one big family for that short time, everyone helping each other get through this terrible tragedy'.
4. 'Still miss my friends. Still having trouble breathing. Still having nightmares. A decade later, my country is paralyzed by the political conflict most visibly symbolized by a building not yet finished after a decade of bickering and infighting. The jobs that would once have been centered here have long since moved on, never to return.
5. 'I could not have been more proud of New Yorkers that day. People assisted older people and pregnant women. Shopkeepers came out of their stores handing out bottles of water as we came into Queens. That day will never be forgotten'.
'We all ran outside of our building when we heard the terrible noise. As I exited, I saw what seemed to be hundreds of thousands of people running. At that moment, it looked like when the bulls of Pamplona are released.
That experience will never leave my memory. Every time I see a plane in the sky in an urban setting, my thoughts go back to that day'.
6. 'I was a serving member of the R.E.M.E. (Territorial Army) at that time. I was on annual camp in a British Army barracks in Germany, and we'd just come back from the field after a 7-day exercise.
We watched, along with the rest of the world, as the jets smashed into the buildings. It was shocking to say the least, and we all felt vulnerable - because an attack of this scale could have meant further attacks, particularly against military targets. It was a very worrying and sad time for millions of people around the world'.
