 In August 2001, Mihdhar and Hazmi made several visits to the library at William Paterson University in Wayne, New Jersey, where they used computers to look up travel information and book flights.On August 22, Mihdhar and Hazmi tried to purchase flight tickets from the American Airlines online ticket-merchant, but had technical difficulties and gave up.Mihdhar and Moqed were able to make flight reservations for Flight 77 on August 25, using Moqed's credit card; however, the transaction did not fully go through because the billing address and the shipment address for the tickets did not match.
