Circuit breakers
Same questions being asked in the AV Herald comments, and also whether that breaker is on any checklists. Remember it is not directly the landing gear alternate system breaker, but an upstream bus breaker which happens to supply the alt gear as one of its loads, so unless you know the systems well, it does not jump out at you as the breaker to check. Nevertheless, (1) sighting the breaker panel, you would normally notice any popped breaker (surely? see the photo on AV Herald), and (2) they were evidently in contact with the ground crew who should have been able to research the systems if required.
The next point is risk and policy for resetting a breaker in the air. A breaker normally trips for a reason (unless it is manually pulled - accidentally or intentionally), so resetting it does present a potential fire risk which is not desirable when you are in the air. On the ground it becomes an entirely different consideration - push the breaker and see what happens.
