The Army Black Hawk helicopter that collided with a passenger jet near Washington on Wednesday was training near a busy airport, and in a complicated airway, because Army helicopters frequently ferry cabinet officials, lawmakers and other V.I.P.s across the area, Army officials said on Thursday.
The Black Hawk crew was among the Army’s most experienced, consisting of command pilots belonging to the 12th Aviation Battalion out of Fort Belvoir, Va. Those pilots routinely conduct both daytime and nighttime training runs in an air corridor next to Reagan National Airport.
