I suspect it's significant that Atta missed that court date on May 28 (and a warrant was issued for him a few days later).

Yeah, he may well have been out of country at the time.

Keep in mind that whatever time frame we set up has to be consistent with both known facts and likely post-Prague, especially if we view the Prague meeting as being necessary for his trip to Iraq. Going on my earlier thoughts, if we have Atta picking up anthrax in Iraq, does anyone have a general date cited by the doctor who said that he (Atta) may have been exposed to anthrax?
