You saw the movie.
You know how.
Now you know WHY.
Actually I haven't seen the movie - but of course Wiki gives the whole plot. I could tell from your graphic that it was when the World Trade Center was still standing. That always brings back memories as I stood on the roof of the South Tower in the 70s. The construction was almost completed (there was still construction debris scattered around) and we were putting up an antenna (for ABC News).
An amazing memory. My whole memory of New York is amazing in light of what it has become. I have no desire to go back❗
