Taikonaut
The MD-11 already has the range and payload of the classic. No need to take on an old plane with mx problems when you already have MD-11's in that market. The one advantage the classic has is the ability to put in a taller pallet. That's an advantage if you're going to bulk out before you gross out. The -400's World "may" be getting will be converted pax planes so they will be quite a bit cheaper than those flown by Atlas.
