The International Air Transport Association (IATA) urges the U.S. Department of Homeland Security (DHS) and the Transportation Security Administration (TSA) to partner with industry to identify the most effective and efficient ways to address the evolving security challenge in light of the foiled terrorist plot to down a Detroit-bound airliner. In a letter to DHS Secretary Napolitano, IATA’s Director General and CEO Giovanni Bisignani discussed the need for short-term temporary and extraordinary security measures until the immediate threat has abated. But he cautioned Napolitano that long-term solutions must include improved technology and effective risk assessment techniques.  “The air transport system cannot support 100 percent  pat-down searches over the long term.” IATA is recommending a smaller percentage of intensive pat downs accompanied by technologies or proportionate screening procedures as a means to achieve near-term security requirements with reduced delays.
