I heard that the Ethiopian Air ran out of fuel due to draining one of the tanks with fuel still left in the other (forgot about the cross-feed being open maybe?) That's why it dropped the wing. Can't blame him though, as his FO had a fire axe through his head. Not much cross-monitoring going on.
Also heard one about a US C-130 successfully ditching in the sea. The Air Force / Navy decided to run a trial by deliberately ditching another C-130 to study the effects. Unfortunately everyoe died. Don't know if it's true or not.
