I remember rather vividly how the networks were scrambling to find relevant people to interview to get their opinions. Fortunately Fox was able to get Newt Gingrich on the phone within perhaps 30 or 40 minutes of the first attack. Fox was interviewing him well before the South tower collapsed. As a professional historian he had really keen insight about the situation. He called it the "Pearl Habor of the 21st century." At the time people were just beginning to die; nobody knew how many people would die, but based on the number of people who could have been in those buildings he thought the numbers could possibly approach those of Antietam or Gettysburg.
