WB Bach has summed it up perfectly. Airline safety departments are all about brand protection. Jetstars benchmark for how safe they are is the number of safety reports they receive. Under their strange logic the more reports they receive the safer they are! If they think that keeping quiet about incidents is good for the "Brand" then that is just confirmation of the warped thinking that permeates HO.
Last time I saw GK he was still working for Jetstar.
