aussiedigger, to answer the questions not already covered!
The 747s are called "Classics" because they are the older model, 'classic' aircraft as opposed to the newer Glass-cockpit -400s. They carry a completely different endorsement, and flight engineers...
NLH is in all white livery now because the yanks couldn't recognise it as a Qantas aircraft, and is due to stay until Sept next year (I think). Technically being repaced by the ERs as they come.
I think the -ER GEs are rated at 65000... Of course the most noticable difference between the RR and the GE is that the GE takes about a third as long to start!
