am aware of only 1 case of a 2-system hydraulic failure on a 747, and no cases of a complete, 4-system failure.
Then there was the Pan-Am 747 that lost 3 hydraulic systems on take-off, came back and landed and the whole thing was captured on film.
With only 1 system he did not have quite enough elevators to flare and hit pretty hard, bounced and came back down in one piece.
After shutting down, the airplane tipped over on the tail as the body-gear was still retracted.
