Not really that hard? Did you read that even the air-con is sperated? it's simple on the surface but complex and detailed once you get into detail. I don't see anything about that in there.

Re: Why was the 747-500 cancelled?

A few years later, of course, Qantas got their 747-400ERs. More fuel and more strength for more MTOW and range.

The market for an actually larger aircraft just wasn't there.

They're buying more 787s anyway, so that will take up some staff with a reasonably small amount of retraining. Presumably a reasonable amount of the 787crew are qualified (though lapsed) on the A320 as that will have been the training pathway since the decline in 737s.
