Commercial Aviation: Status of Air Service to Small Communities and the Federal Programs Involved
GAO-14-454T: Published: Apr 30, 2014. Publicly Released: Apr 30, 2014.
Air service to small communities has declined since 2007 due, in part, to higher fuel costs and declining population, and for some communities, compounded by more attractive service (i.e., larger airports in larger cities) within driving distance. In fact, airports of all sizes have lost capacity in the number of available seats, and largely for flights as well. However, medium-hub and small-hub a...

F-35 Joint Strike Fighter: Slower Than Expected Progress in Software Testing May Limit Initial Warfighting Capabilities
GAO-14-468T: Published: Mar 26, 2014. Publicly Released: Mar 26, 2014.
Delays in developmental flight testing of the F-35's critical software may hinder delivery of the warfighting capabilities the military services expect. F-35 developmental flight testing comprises two key areas: mission systems and flight sciences. Mission systems testing verifies that the software-intensive systems that provide critical warfighting capabilities function properly and meet requirem...
Whistleblower Protection Program: Opportunities Exist for OSHA and DOT to Strengthen Collaborative Mechanisms
GAO-14-286: Published: Mar 19, 2014. Publicly Released: Mar 19, 2014.
The Occupational Safety and Health Administration (OSHA) has taken steps to include auto industry employees in its Whistleblower Protection Program and has coordinated with the Department of Transportation (DOT) on whistleblower issues, but interagency collaborative mechanisms could be strengthened. Among other steps, OSHA is developing procedures for how it will investigate claims from auto emplo...

GAO-14-15: Published: Nov 6, 2013. Publicly Released: Nov 6, 2013.
To assess the risks and potential effects from disruptions in the Global Positioning System (GPS) on critical infrastructure, the Department of Homeland Security (DHS) published the GPS National Risk Estimate (NRE) in 2012. In doing so, DHS conducted a scenario-based risk assessment for four critical infrastructure sectors using subject matter experts from inside and outside of government. Risk as...
