Two US Copters Fired Upon: Two U.S. helicopters retrieving the wreckage of a downed Black Hawk helicopter managed to return safely to their base after coming under light fire in Pakistan on Monday, a Pentagon spokesman said. The crewmembers had prepared the wreckage for transport, but left the load at the site for a preplanned refueling. The recovery crews were at a nearby Pakistani airfield refueling when they encountered "light and unorganized" retaliation fire from somewhere near the airfield, said Lt. Col. George Rhynedance. Pentagon officials don’t know who shot at the crews, he said.
