Hard to remember much about specific airframes as an engineer, bit I seem to recall that 66 was the last aircraft to make it out to Akrotiri for GW1. It had been in at NMSU for a major and then rushed through EWAD to join the party.
NMSU and EWAD had surpassed themselves with this one, it was a complete bag of sh!te, including leaking like a sieve when it arrived.
It was a long time ago now and I could have the wrong aircraft, but I'm sure one of the crew can confirm from their logbooks.
