Whose is the 747 Classic (possibly cargo?) with winglets which I watched depart STN recently? White fuselage, plain dark blue fin, no other obvious markings.. .. .Not a sight you see every day. What's the story?

KC,. .. .Don't think there are any "Classics" with winglets. What you have probably seen is a -400F,. .as they have shortened (like a "Classic") upper deck

You're right, of course...do I feel sheepish now. <img border="0" title="" alt="[Embarrassed]" src="redface.gif" />

Ah but just imagine a Classic freighter with the add-on 'bendy bits + Trent 500's hung under the wing. . .. .Keep the F/E in place for his fund of stories,tea making skills and the ability to draw on his deeply ingrained knowledge of all things mechanical when things go t*ts-up.. .. .Oh and yes - he can also fight a main-deck cargo fire which can be a bit of an iffy exercise on a two crew 400F.. . . . <small>[ 12 March 2002, 10:47: Message edited by: Fr8t M8te ]</small>

It has already been decided that the structural requirements for adding winglets that are large enough to be worth it in cruise are far to great to be economically feasible. API flight tested 14 ft tall ones last year on a -70A powered ex FedEx freighter.. .As far as the re-engine part goes, the Trent 500 is probably marginal on a 747. Boeing Airplane Services already has a master change for CF6-50/CF6-80 re-engine for the Classics and there are some flying. The Trent is a digitally controlled engine that takes massive cockpit changes to make work and in the end would eliminate the FE(Glass Cockpit, 2 seater). The CF6 can be either digital or analog so very little changes are needed in the Flight Deck. I am not sure if they keep the FE after the MOD. By the way the last airline that did this paid ~25,000,000 per airplane for CF6-50E2s. <img border="0" title="" alt="[Wink]" src="wink.gif" /> <img border="0" title="" alt="[Smile]" src="smile.gif" />

The paint scheme sounds like on of Atlas Airs, seen that a few times in NY.
