Even in the case of Japan Airlines Flight 123 (https://en.m.wikipedia.org/wiki/Japan_Air_Lines_Flight_123) the pilots still had some degree of control over the plane after its tail was ripped off due to a structural failure leading to explosive decompression at cruising altitude which also caused a total loss of all hydraulic systems.
Unfortunately what they had left (control over the engine thrust) was not enough, but they sure did their best. Apparently you can still control (to some extent) the plane using just the engines, with and the vertical stabilizer being completely gone, and no hydraulics. And this was in 1985.
I’m not saying that JAL 123 was in any way survivable (although some miraciously did survive), just pointing to the fact that even in the worst possible scenario there’s still probably a way to somehow control the plane.
