Funny how certain events stay engraved in our minds forever and are triggered by visual means for the rest of our lives. I was living in New York at the time of 911 and had witnessed the whole disaster from the rooftop of my downtown Nolita office. It was horrific to say the least seeing that and experiencing it so closely. Since then, seeing a plane next to a high rise triggers a stream of unwelcome memories and emotions.
