Yep. Or a fire—I keep thinking about that Swissair flight because their fire was in the wiring, and gradually disabled all the electronic systems and instruments on the MD-11, in addition to spewing toxic smoke into the cockpit.

The investigation on that flight took four years and $40 million, and that wreckage was near to shore in 180 feet of water. I expect that will be dwarfed by the investigation on AF447 just by the sheer logistics of where and how deep it is. Sadly, there’s a very good chance we’ll never know what happened, and almost no chance that bodies will ever be retrieved.

True. And if there were a fire that affected the signals being sent to control actuators, that would perhaps show up as "turbulence."
