But it suffered the same kind of failure as flight 232. Lockheed had the foresight to use quad redundancy.

From Wikipedia:

On September 22, 1981, an Eastern Airlines Flight 935 departed Newark, New Jersey and suffered an uncontained failure of its number two (tail) engine at 14,500 feet (4,400 m), while en route to San Juan, Puerto Rico.[64][65] The fragments from that engine damaged three of its four hydraulic systems resulting in fluid loss in them. The rudder pedals also jammed. The fragments impacted but did not puncture the lines for the other hydraulic system; the captain was able to safely land the aircraft at John F. Kennedy International Airport, with some limited use of the outboard spoilers, the inboard ailerons and the horizontal stabilizer, plus differential engine power of the remaining two engines. There were no injuries. The L-1011 having four hydraulic systems (instead of three like the DC-10) allowed for a safe landing"
