Triple system failure https://en.m.wikipedia.org/wiki/United_Airlines_Flight_232 https://en.m.wikipedia.org/wiki/United_Airlines_Flight_232
“The crew contacted United maintenance personnel via radio, but were told that, as a total loss of hydraulics on the DC-10 was considered "virtually impossible", there were no established procedures for such an event.”

By using each engine independently, the crew made rough steering adjustments, and by using the engines together they were able to roughly adjust altitude. With no control surfaces, and using the engine thrust they attempted a landing - of the 296 people on board, 111 died.
