Well in Britain we don't reward people for doing their job. If you keep an aircraft flying for 76 missions, that's your job. That's what you're supposed to do, you're doing it well, and that's what is expected.
If an aircraft technician was working on an aircraft and the base came under attack then the person got on a MG and defended the place, he would be rewarded because defending the base isn't his job but he did it. That deserves a medal. Even then he might get in trouble for leaving his post because getting that aircraft in the air is his priority.
