An excellent Pilot / Instructor I worked with on Herks who had a promising career as a FJ but very nearly died playing "carrier landings" ... I believe he slipped on spilt ale and went face first into the end of the table, at a great rate of knots ..... only the fact that several PMRAFNS ladies were in attendance, and sober, saved his life. He did need several major operations and wore the scars from then on.
I was always grateful that the SNCOs Mess did not indulge in such self-inflicting injury type "sports" ....
