Incident: Lufthansa B748 Near Frankfurt on Oct 24. 2015, Hydraulic Leak

A Lufthansa Boeing 747-800, registration D-ABYN performing flight LH-754 from Frankfurt/Main (Germany) to Bangalore (India), was climbing out of Frankfurt when the crew stopped the climb at FL230, descended the aircraft to FL200, dumped fuel and returned to Frankfurt for a safe landing on runway 25C about 90 minutes after departure. The aircraft taxied to the apron with emergency services in trail.
