I was actually on the phone with a customer who saw the first plane hit. We were on an early morning conference call, when he interrupted and said - " umm, guys, I’m going to have to drop off the call - I swear I just saw a plane crash into the other tower."

I was thinking “man - must have been having some kind of mechanical failure and crashed before they could get to the airport - that’s terrible.” Then, the 2nd tower got hit, and I knew it wasn’t just an accident or mechanical failure.
