ACARS747 sounds like one of those Impulse 1900/717 drivers that live in their sheltered little enclave in Jetstar. The same guys that loath and backstab the ex Ansett guys for wanting to raise the bar and improve the standard at Jetstar, knowing full well that the next sim they do, may be a bit harder and out of the protective realm of their Impulse buddies.
The only thing the Jetstar "boys" can teach the rest of the Qantas group, or industry in general is how to be an Aero Club operating Jets and how to sell yourself out from poor advice and pressure from management and the JPC.
