A Los Angeles news helicopter crashed and caught fire Tuesday evening, killing at least three people near Prairie Street and Lurline Avenue. The aircraft was later confirmed as belonging to KNBC, the city’s NBC station, while the crew was covering another deadly crash. The helicopter slammed into the ground and ignited several vehicles, sending a huge column of black smoke over the area. The names of the people aboard had not been released, and officials had not announced what caused the crash. What Happened at the Scene? The news crew had been following coverage of a fatal bus crash that reportedly killed at least two people. During live coverage, KNBC anchor Coleen Williams told viewers that the station had lost contact with its team. “Lost contact with our people.” NBC4 anchors appeared visibly shaken while reporting from the scene, and the station said it would step away from the broadcast to process the tragedy. The National Transportation Safety Board is leading the investigation as officials work to identify the victims and determine how the helicopter went down.
