A Pakistani businessman called Mohammed Atta (spelt with three ‘m’s) arrives in Prague aboard a Lufthansa flight from Saudi Arabia via Frankfurt. As he does not have a Czech visa, he is sent back, although he remains in the transit area at Prague Ruzyne airport for six hours. Unfortunately, he spends most of his time at the airport out of range of the security cameras. In the confusion immediately after 9/11, Czech counterintelligence will believe he may be the real lead hijacker Mohamed Atta (spelled with two ‘m’s)—he paid cash for his ticket and names are often spelled wrong—and that he had a meeting that could not wait, although this theory is eventually discounted. The real Mohamed Atta has a Czech visa, but it will not come into effect until the next day. Atta arrives in Prague on June 2 (see June 2-3, 2000).
