Training mission doesn’t mean trainees. And if wouldn’t be three trainees if it was new pilots. If would have been one instructor, with one pilot being trained. But even if it was three highly experienced crew members that had been flying the area for years, it would still be a training flight.

All speculation at this point, but any training flight would require one's attention to not be completely focused but rather split here and there, I would imagine.
