The tests were conducted in two phases. Phase one screened checked baggage bound for international destinations. Phase two tested carry-on items on both domestic and overseas flights. Each phase took place on a separate day with average volumes of passengers booked on the flights.

Statistics from each phase were recorded separately and are shown that way in this report. Collectively, these statistics provide valuable information and will help in the design of better

airport security systems.
