Deaths in the Navy

My ex-boss Jerry served in the Navy on an aircraft carrier for a while. During his stay on the ship, at least four crewmates died:

Two accidentally ejected from their aircraft into the ocean, never to be found.

One died in a storage room in the bowels of the ship by asphyxiation - apparently there was a buildup of carbon monoxide or dioxide down there, and generally men went there in pairs because they could get "sleepy."

One officer nobody liked turned up missing, and they never found him. Jerry thinks someone pushed him overboard.
