FED,
It depends upon what the problem is doesn't it?
It could be like in Nigeria where a 76 crossed the deck edge upon landing and the flight controls locked up.
The Pilot flying elected not to fly the aircraft home.
Another pilot got dropped off, climbed into it, and took off for home.
Major problems found with the aircraft back at Base and it was in the hangar for more than a few days.
But then....he made it home so I guess he was the Hero to Management that day.
