She wasn’t conducting training. She was being certified by the more experienced WO for continuing training, an ongoing part of all pilots staying current. Night vision and this flight route we not selected by her, as the trainee, or by the Pilot performing her training. We don’t know yet who had the collective in-hand before and/or at the moment of collision.
That was a slip of the phrase, I understand she may have been the trainee. Regardless, they were conducting a training exercise in that airspace which I consider insane and the evidence bolsters my opinion.
