Congress has failed to resolve a budget impasse that has left thousands of Federal Aviation Administration employees out of work for nearly two weeks. The House and Senate began a five-week recess on Tuesday without coming to an agreement on FAA funding. The stalemate centers around money for rural airports, but Republicans have also attempted to alter rules on labor elections in the airline industry. Tens of thousands of construction workers have been forced to halt work on airport construction projects, and dozens of airport inspectors are working without pay. Although the stalemate could extend through Labor Day, the federal government insists passenger safety is not at risk.
