Drone crashes mount at civilian airports 30 Nov 2012 The April wreck was the latest in a rash of U.S. military drone crashes at overseas civilian airports in the past two years.

A review of thousands of pages of unclassified Air Force investigation reports, obtained by The Washington Post under public-records requests, shows that drones flying from civilian airports have been plagued by setbacks.
