All those names were Bankstown flight ops & AWI's at the time.
Was Pel-air managed from CASA's Mascot office at that stage, or from the GA office at BK? With the SAABs, Metros and Jets I would have assumed that the Mascot office had more appropriate expertise.
Outside the BK office, Ben Cook (now back with DILLIGAF or whatever the RAAF human factors office is called) is a very capable guy and I doubt there would have been any fear or favour colouring his audit findings.
