United Airline DC-10 crash at Sioux City airport further to total loss of hydraulic power
What happens in this video ?
On July 19, 1989, this United airline DC-10 crashed at Sioux City airport (Iowa, USA).
The cause of the accident is that
the fan disk of its tail-mounted engine, weakened by fatigue cracks, fragmented catastrophically, and the engine assembly
failed to contain the debris which severed all three of the airplane's hydraulic systems. It had left all control surfaces
on the airplane immovable. The only way to control the plane was by adjusting the thrust on the two remaining wing-mounted
engines.
During the emergency landing, the right wing dropped and the nose pitched forward. The tip of the right wing
contacted the runway first and the aircraft skidded to the right, ignited and somersaulted. 184 passengers survived, 112
passengers died.
