and pete ganci was just down the hall and he yelled, "look out the window, a plane just hit the world trade center." we could see it from our windows. - i was sitting in my office, and my office looked at the trade center. and i saw the plane go into the building, saw a fireball come out, and saw the smoke come out. i get up, go right into bill's office, said, "i think a plane crashed into the trade center." myself, bill, tom fitzpatrick, we all went down to the garage, got into bill's car. as we came out, we have people running all over brooklyn already. and i'm saying like, "what the hell is going on here?" - [tom] pete stopped the car, and we got out, and started to head towards the plaza. bill and i were just near the big ball, these sphere. the sound of a plane coming down. - bill was at the back of the car with tom fitzpatrick, putting their coats on. i just remember hearing that roaring noise. (explosion) - and when it hit the building, i never saw it, because i don't think bill saw it either, in full scale. we just both were sort of looking that way to get hit by something. -
