@bec.news: Newly released air traffic control audio captures the harrowing final 30 seconds of flight N722BD before the private Learjet 60 plunged into Palm Beach County, Florida, killing all nine people on board. The emergency recording reveals the crew desperately reporting severe icing, an overspeed condition, and a catastrophic descent rate exceeding 20,000 feet per minute while the air traffic controller attempted to guide them until the final cockpit transmission ended. #FloridaPlaneCrash #ATCAudio #Learjet60 #N722BD #AviationNews
