Not just a flip flop ...

... but a flat out lie.

Found this on Salon today:

In a question-and-answer session in December 2001 -- just three months after the attack -- Bush remembered watching the first plane hit the World Trade Center while he was waiting to enter that classroom in Florida. "I was sitting outside the classroom waiting to go in, and I saw an airplane hit the tower -- the TV was obviously on," Bush said. "And I used to fly, myself, and I said, 'Well, there's one terrible pilot.' I said, 'It must have been a horrible accident.'" Bush repeated the story at another event in January 2002.

The only problem is, it never happened. The first attack wasn't broadcast live -- who would have known to show it? -- and videotape of it wasn't available until much later. Bush may believe the words he says, but there's no way he saw what he said he saw.
