The National Transportation Safety Board (NTSB) found no evidence of foul play and blamed the crash on errors by the pilot, who failed to retract the plane’s spoilers, or air brakes, at the critical stage of the descent, causing the plane to stall and crash 1.5 miles short of the runway.

A 60-passenger jet collided midair with a Black Hawk helicopter near Reagan National Airport and crashed into the Potomac River.

Twenty-seven bodies had been recovered from the downed plane, a Bombardier CRJ700 operated by PSA Airlines, and one had been recovered from the helicopter, a Sikorsky H-60, said the D.C. Fire and EMS Chief.
