Well- if a skipper wanted back in I'd say they'd take him/her as they are extremely sort. Just depends how they left. (Eg. Not sacked, did they work their notice etc.) as for the FO's their not too short to be fair, and there's noway at this time FR would take them back. For FO's this rule has been in place for many years now. Unless they have the time on type/total time for a command course!
