I can tell you where I was 13 years ago and I will not go into anymore details of that day...
13 years ago on that day, I was at work early, sitting at my desk getting ready to enjoy an omelette breakfast before starting my actual research work on the 8th floor in NYC, only a block away from the WTC and in just a short time my whole life changed forever... The building I was in shook as if, it was hit by something too... After the first plane, no one really did not know what was happening, but we were in a hyper- alert state, but it did not dawn on anyone to run out of the building, it was when the second plane hit was when the building Security (in a calm voice) on the intercom told everyone to get out and not get on the elevators. The receptionist in my building, an elderly woman was trying to run down the stairs and had a heart attack and I heard, the medics had to go in and get her. She survived and retired, never coming back to work again, but I heard sadly she did died in 2008.
Once reaching outside, that is where all havoc happened and actually being there to see that scene of devastation was mind blowing and the pure adrenalin that kicks in your body when you are trying to survive and get home is amazing,,, I am going to end it right there...
I remembered, NYC being closed down for about 2 weeks and my job allowed us to take 3 weeks off with paid and all the counseling that was provided and my job site was moved from the Financial district to Mid-Manhattan or the Theater district of NY. That was my experience of 9/11...
PS: We did not know in that moment that planes hit the WTC, many of us running the street thought that NYC was being bombed, it was only until I got home and saw it on TV, I realized those were planes...(Just wanted to add that in the mix to those who saw it only on TV and was watching it, many of us, were running because we were afraid of bombs--)
