Pilots Switched Controlling Before a Rough Landing The change occurred at an altitude between 200 and 400 feet, which is extremely low for such a shift, according to airline pilots. The safety board did not explain why the change was made. Investigators may have clues from the cockpit voice recorder and the flight data recorder. The nose gear of the plane, Flight 345 from Nashville, collapsed upon landing, and the aircraft, a Boeing 737, slid about 2,000 feet down the runway. Eleven people on board the flight, which was arriving from Nashville, were taken to hospitals. The safety board said that the plane was at the proper speed, descending at the proper rate and on the proper course "down to about 200-400 feet." "At this point, no mechanical anomalies or malfunctions have been found," the board said. A plane's captain and first officer generally take turns landing, one as the "pilot flying," with his or her eyes toward the runway, and the other as the "pilot monitoring," which includes watching the instruments. The safety board said that the captain had extensive experience as a 737 captain, but had flown to La Guardia only once before. The first officer also had extensive experience in the 737, and had landed at La Guardia six times in 2013, the board said. On July 22, however, planes were landing in an unusual configuration for La Guardia that required them to come in low.
