So we were fairly fortunate to be on the front. After finding a stairwell, they managed to get to the lobby where port authority officers and fire crews were trying to organise people to get them out of the building. They did not want to waste a minute so they found the east side of the building and headed into the courtyard and then over towards the street.

We got knocked down to the floor and we were behind a desk when it blew in over the top of us.
