Danbury Municipal Airport is one of five facilities in Connecticut to share in $4.6 million in airport safety and infrastructure grants from the federal government.  Danbury will get $157,500 to fund studies of obstructions to aircraft approaches and airfield wind coverage.  Funding is also being provided to Bradley, Tweed-New Haven, Sikosrky and Meriden airports.  In addition to the funding announcement, U.S. Department of Transportation Secretary Elaine Chao announced that the agency is working to streamline the approval process, cut unnecessary red tape and reduce duplicative regulations that do not contribute to safety.  According to the Federal Aviation Administration, U.S. civil aviation supports more than 5% of U.S. gross domestic product; $1.6 trillion in economic activity; and nearly 11 million jobs.
