What we're covering here
• 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 Wednesday night’s fatal 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.
• New videos of collision: The National Transportation Safety Board has recovered the flight data and voice recorders, known as black boxes. Meanwhile, videos obtained by CNN show previously unseen angles of the collision – the deadliest for US carriers since 2001.
• 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.
