Justin Sellers, left, an unmanned air systems flight operator, lands a Puma unmanned aircraft system as fellow operator Stu Orozco looks on aboard high speed vessel Swift (HSV-2) April 25, 2013, in the Caribbean Sea near Key West, Fla. The Puma?s flight was part of an at-sea demonstration of future counter-transnational organized crime operations as part of Operation Martillo. Martillo is a joint, interagency and multinational collaborative effort to deny transnational criminal organizations air and maritime access to the littoral regions of the Central American isthmus.
