FILE - In this March 5, 2010 file photo, U.S. Marines help a wounded comrade onto a Black Hawk helicopter, left, during a medevac mission by the U.S. Army's 82nd Airborne's Task Force Pegasus, as a chase helicopter flies for security, right rear, in Helmand province, Afghanistan. America's wars since the attacks of Sept. 11, 2001 have been a boon for the maker of Black Hawks. Sales at the Stratford, Conn.-based Sikorsky Aircraft Corp., more than doubled in five years, to $6.7 billion in 2010, due in large part to the company’s military business that includes the Black Hawk.
