Big airplanes will often do transition work (Pilot Proficiency), at the end of a Tac sortie to get "counters" for the AC/CP/Nav. In the gunship the Tac crew usually wanted us to land and download them rather than sit through an hour of ILS/LOC/TAC/ASR approaches. It takes 15 minutes or more to land, taxi back, open, download, close, taxi back, and takeoff so many pilots just keep the tac crew on board...at that point the grump Tac crew calls it "Hostage Pro". My personal rule was if it was going to be less than an hour or we were doing Tac approaches, they stayed.
