Great question rude.....
Personally, I like to try and fly to maxmimize the effort, but minimize the cost. In other words, I try to pretend that it's a true "one life" simulation and fly to achieve the mission, but return the equipment and myself in one piece to fight another day. Unfortunately, I often see one of my buddies in trouble down low and screaming for help, so I usually wade into help him and die in the process. It would be an interesting real life dilemma.
