j3,
I've travelled on the A330 a number of times to the Middle East (last time was in early 2008)
Not sure if its still the case, but in addition to the Tech Crew (all in white shirts) was another crew member wearing a blue shirt with 2 or 3 bars. After a short converstaion, he informed me he was from Flt Ops and it was a company requirment to wear the uniform.
Must say overall I was very impressed with the Tech and CC. When we arrived back in BNE, the Flight Services Manager made a PA and gave a very warm thanks to all of the ADF personnel on board. We may not have said it to each other at the time, but that simple thanks did mean alot.
