What we're covering here
• Black boxes recovered: Authorities have recovered a combined voice and flight data recorder from the US Army Black Hawk helicopter involved in Wednesday’s deadly collision with an American Airlines regional jet. That gives investigators a complete set of recorders: The NTSB said earlier that it also recovered the jet’s two black boxes.
• FAA action near airport: The Federal Aviation Administration has indefinitely shut down the low-altitude helicopter corridor that was in use at the time of the midair collision near Reagan National Airport, an FAA official tells CNN. Just a day before, another flight was forced to abort its first landing after a helicopter flew near its flight path.
• Recovery operation: Crews have recovered 41 bodies from the collision site, and 28 of them have been identified, according to fire officials. The jet, flying from Wichita, Kansas, was carrying 64 people, while three soldiers were aboard the helicopter. All are presumed dead. A groom-to-be pilot, a daughter of Indian immigrants and figure skating champions were among the victims.
