Boeing 737 Next Generation
Turkish Airlines Flight 1951 crashed while landing at Amsterdam Schiphol Airport on February 25, 2009. Investigators later discovered that one of the altimeters, which show how high the plane is flying, was wrong. This led the autopilot to switch the engines to "idle", and the engines only produced a small amount of thrust. As the plane flew on, it eventually stalled, and started descending. The pilots did not realise this until the warning started, and did not control the plane properly to recover from the stall, causing the crash. 9 people were killed.
