Forty years ago I was on a commercial flight in a DC-6B that mysteriously turned around and began returning to the point of origin. About this time some of us noticed oil dripping off the trailing edge of the wing. Just before we landed, the aircraft had a few heavy duty shudders.
We heard that by the time the problem was discovered, the engine had gotten too hot to shut down and the captain opted to keep it running in spite of the rapidly disappearing oil.
I understood that what had happened was that the first mechanic's habit was to tick off the things he intended to do, one of which was to tighten that oil plug. In any case the aircraft engine was heavily damaged (if not junked) and the mechanic was soon looking for work.
Bad things happen.
