On 24 March 2015, suicidal co-pilot Andreas Lubitz deliberately locked his Captain out of the cockpit and initiated a purposeful descent of Germanwings Flight 9525 resulting in the death of 150 people when the plane hit a mountain at 700km per hour.

On 28 December 2014 Indonesia AirAsia Flight 8501 departed Indonesia for Singapore with 162 people on board. An hour later, after requesting permission to deviate from their route to avoid thunderstorms, all communication with the plane was lost.
