The pilot in question's back went out as he attempted to lift his nav bag out of the confined space next to his seat. He now is crippled by the injury and unable to work. It happened while on duty. He is entitled to compensation. Some of you are a heartless lot.
I know of a captain that while twisting in his seat and reaching up and behind him to locate his headset, buggered his back so painfully that he had to be carried off the aircraft. He was out of action for several weeks despite visits to the medicos and acupuncture treatment.
Maybe he should have sued the airline for making the headsets hard to reach without twisting? Where does it all stop?
