The Implementing Recommendations of the 9/11 Commission Act of 2007 mandates the Department of Homeland Security (DHS) to establish a system to physically screen 50 percent of cargo transported on passenger aircraft by February 2009 and 100 percent of such cargo by August 2010. This testimony provides preliminary observations on the Transportation Security Administration's (TSA) progress in meeting the mandate to screen cargo on passenger aircraft and the challenges TSA and industry stakeholders may face in screening such cargo. GAO's testimony is based on products issued from October 2005 through August 2008, and its ongoing review of air cargo security. GAO reviewed TSA's air cargo security programs, interviewed program officials and industry representatives, and visited two large U.S. airports.
