Yes, I agree. In the transcript of a discussion with reporters on board AF1 he said this...
"I even went up to the cockpit and watched Tillman bring it in -- which, had the security been broken there would have been the time that we would have been most vulnerable. However, the plane -- that's why Colonel Tillman's judgment was so important to this -- this plane is protected, it's protected against the kinds of things that could be used against it. It also -- we obviously flew in, in the dark, precautions were taken."
He certainly seems to be implying that he was aboard AF1 when they landed in Baghdad. I wouldn't think that he would lie about something like that after the fact. It would serve no good purpose that I can discern. In fact, it could be used against him if it can be proven that he lied like that.
