AA DC-10 had a jammed stabilizer. Not the same as a total hydraulic loss but they were able to land using the #2 engine to change the pitch attitude. Using the wing mounted engines also has a pitching moment(power up, nose up, power back, nose down)
DC-10 into KSUX had total hydraulic failure. Read the NTSB witness statements, and not the final report. CKA Dennis Finch(sp?) saved the day.
A300 had total hydraulic failure after SAM impact. Did one go-around and then landed on the runway.
Total hydraulic failure is possible. It can be survivable but is tough to accomplish. I'm 2 out of 3 in my attempts. Fairly easy, very tough, and then a crash.
Try it and be humbled...
