I was told a story by a Canadian Forces mechanic about how he used a hand drill to do some underwater repairs on a float plane pontoon while in a remote area up North. I'm not sure if hand powered tools are part of a standard repair kit for the Canadian military or if he was just being extra cautious in including some in his kit, but one can see how they could be useful when working in remote areas without power.
