BV, we had a chap, second tour on type but a change from high level to low level who decided that enough was enough. Probably many causes but nuclear weapons was probably not one.
I don't know the process as he left the sqn while I was away but he was grounded, re qualified in a different branch and subsequently joined a different service. It appears probable that the system treated him well but he acquired the nickname ' chicken nnnnnn' from his previous colleagues. How times have changed.
