I wonder how they must have felt to have coded a 9/11 scenario of Arsenal Gear crashing into the Twin Towers, and then watched it actually happen a few months later.

This was cut from the game but is still in the source code leak, just commented out! https://www.youtube.com/watch?v=DNSPx-oRV60

Also note that the source code was leaked on April 30th :p

At least that was cut from the game. I remember that episode from The Lone Gunmen, the X-Files spin-off series, where they stopped the (inside job) hijacking of a commercial airplane from crashing into the twin towers, which aired just a few months before the attack.

I only watched it a few years later, and I had to double check the airing date.
