I once sat in a jumpseat for two hours with my jaw broken in eight places and needing surgery as soon as we landed. (This is a true story). Technically, the crew could have not allowed me on since you could have considered my medical invalid at the time, so I was grateful for the ride... but my face was swollen to two to three times its normal size and neither pilot once even asked me if I was alright or what happened or anything at all!! Hahah. I was clearly in pain and mentioned I needed surgery as soon as we got to where we were going. They never said a word to me the whole entire flight, just talked amongst themselves. They were both under 40, the FO was probably 25-29.
