The Capt's for these trips will all be very senior. It's a non-standard operation, with a purely visual approach, and no proper runway markings, etc. So in other words the Capt's are hand picked. As for the F/O's, I requested this trip, but for the most part, the F/O's are assigned off the standby list, or it will just have appeared on their roster. As it turned out, it was a great experience, just sad to see such a great a/c scrapped.
We operated heavy crew to MAN the day before, then just 2 of us MAN-Bruntingthorpe the next day. Transport provided to LHR, then back to HKG a day later.
As spanners mentioned, Engineering does some basic prep and item removal from the a/c before the dismantlers take over, but as for us crew, we just shut it down and set the park brake and that's it.
