I'm sure they were ordered back ASAP. There is an immediate post-crash checklist that goes on with the flight crew. Toxicology, physical inspection, initial debrief, etc.

Don't pin these guys as cowards, don't care, or "going back to safety". They do some of the most dangerous flying in the world.

Or do you do something more dangerous than flying a tilt-rotor aircraft at night in crappy weather/mountainous terrain/dusty brown-out conditions with people shooting at you?
