During WW2, was it an unwritten rule among pilots that you don't shoot at a bailed pilot

That would be U-156, while the air crew did get credit for sinking her, she wasn’t actually sunk, only forced to dive(the difference was of course academic to the people sitting on her deck).
This was later known as the Laconia Incident.

Thanks, Mogle!
