Tuohey was working the U.S. Airways first-class check-in desk when two men, Atta and his companion Abdul Azziz-Alomari, approached his counter. From all outward appearances, the men seemed to be normal businessmen, but Tuohey felt something was wrong.
"I got an instant chill when I looked at [Atta]. I got this grip in my stomach and then, of course, I gave myself a political correct slap...I thought, 'My God, Michael, these are just a couple of Arab businessmen.'"
Atta and Alomari, were flying first-class from Portland, Maine, to Boston, Massachusetts, where they would board the American Airlines flight bound for the Twin Towers.
