U.S. Transportation Secretary Ray LaHood discusses the interruption of federal funding for airport construction projects and contractors at LaGuardia Airport in New York, Monday, August 1, 2011. The FAA's operating authority expired at midnight Friday, forcing a partial shutdown of the agency. Dozens of airport construction projects across the country have been put on hold and thousands of federal employees were out of work.
