The crash of United Airlines Flight 232 came up in a recent thread. (TL,DR: in 1989, uncontrolled engine failure disabled all three hydraulic systems at cruising altitude, pilots could only control plane by varying left/right engine thrust, nursed it down to a crash-landing that allowed 60% of occupants to survive.)
ISTR reading/hearing at that at some point after the crash, this scenario (i.e. a complete loss of hydraulics during cruise) was programmed into a flight simulator, and it was found that no one else was able to successfully control the plane (via differential engine thrust) the way Capt. Haynes and his colleagues did.
Is that an urban legend, or is it true? If true, did the simulator scenario include having the pilots aware from the start that they were supposed to try to control the plane with diff thrust, or did it involve totally uninformed pilots facing a surprise loss of all hydraulics (which would leave them having to figure out for themselves in the space of a few seconds, like Haynes et al., that they needed to try using diff thrust)?
