"I got mad when I, as a national security adviser to the president of the United States, I went down to meet somebody at Reagan National Airport and nobody recognized -- nobody thought I could possibly be the national security adviser to the president. I was just a black guy at Reagan National Airport. And it was only when I went up to the counter and said, 'Is my guest here who's waiting for me?' did somebody say, 'Oh, you're General Powell.' It was inconceivable to him that a black guy could be the national security adviser."
