Dodgybrothers- No different to the way Big Brother did business, not too many Captains are investigators there either. Jetstar do however now have the former head of safety at KLM as well as a former Chief Pilot of Ansett as Group Manager so I don't think they are short of experience. Even before that they had a former ATSB investigator who developed a basic investigator's course because there was no other in-house course available within the Group.
