They are many of the unknown faces working to keep the airline safe,
It would be in Qantas management's best interest to find a hasty resolution and avoid another long protracted dispute... Although few in numbers, the "tech services" or "professional" engineers are also the unknown faces that attempt to minimise schedule interruption... Whether it be quickly assessing skin damage beyond the manufacturers limits due to a wayward cargo loader or lightning strike damage in a ramp environment, to engineering a large corrosion repair in the hangar these guys are integral to the day to day operation of the airline...
I would be very interested to hear more details from the guys involved, and I lend my pen in support...
Cheers.
