Dan,
Going off back to the KC-135, i overheard a comment made by KC-135 crew chatting to KC-10 crew and the comment was about the KC-10 having autonomous throttle control when conducting AR whereas the KC-135 has not?
Something along those lines if anyone can confirm what i'm talking about is correct or complete bollocks.
Going back to FSTA. Saudi Arabia have ordered the A330 now, as did Australia. I Remember a few years ago the BMI A330 with Tonka in tow (and Falcon 20 for taking pics) above my head in AARA10 on a wake turbulance trial (i think). Since then, several air forces have taken up the Airbus apart from the UK where we continue to dither as always about a decision.
