Germanwings Flight 9525 was an international passenger flight from Barcelona in Spain to Düsseldorf Airport in Germany, operated by Germanwings, a low-cost airline owned by Lufthansa.

On 24 March 2015,  an Airbus A320, crashed 100 kilometres northwest of Nice, in the French Alps. All 144 passengers and six crew members were killed, wherein 14 germans students returning in Germany after a school trip in Spain.

French and German prosecutors believe that the crash was intentionally caused by the co-pilot, 27-year-old Andreas Lubitz. Although he had been declared "unfit to work" and was hiding an illness from his employers, Lubitz locked the captain out of the cockpit before initiating a descent that caused the plane to impact a mountain.

In response to the incident and the circumstances of Lubitz's involvement, aviation authorities in Canada, New Zealand, Germany and Australia implemented new regulations that require two authorized personnel to be present in the cockpit at all times.Several airlines announced they had already adopted similar policies voluntarily
