Yes, Lufthansa has had several significant accidents in its long history, with the deadliest being Lufthansa Flight 540 on November 20, 1974. This Boeing 747 crashed shortly after takeoff from Nairobi, Kenya, resulting in the deaths of 59 people out of the 157 on board. The investigation determined the cause to be a failure to deploy the leading-edge slats, which led to a stall. Another notable incident occurred in 1993, when Lufthansa Flight 2904, an Airbus A320, overran the runway in Warsaw, Poland, during a heavy storm, resulting in two fatalities. It is important to distinguish the mainline Lufthansa carrier from its subsidiary, Germanwings; the tragic 2015 crash in the French Alps (Flight 9525) was operated by Germanwings, not Lufthansa itself. In modern aviation, Lufthansa maintains one of the highest safety ratings in the world (7/7 stars on most safety indices) and has not had a fatal accident involving its mainline fleet in over three decades, reflecting the rigorous safety culture of the Lufthansa Group.
