Irrelevant. You are arguing that the "official story" has been changed by the Moussaoui trial exhibit.When a phone calls another phone the provider directs say one seven-digit number to another seven digit number. Very very precise stuff. Would yoou care to tell me how the two seven digit numbers are conjoined and only one is remembered ? In FOUR calls ?
In the 9/11 Commission Report it says there were four calls from Flight 77 to an "unknown number", and that the FBI believes these were from Barbara Olson.
The Moussaoui trial exhibit also says there were four calls to an "unknown number". If they'd attributed the calls to someone else, then why not say that here? They haven't, so there's no reason to believe the FBI's position has changed.
