I've seen references in some books to 3 tiers of -200 A market, with
increasing weights and engine power.  That is seperate from the -200IGW.

Right.  I wasn't sure what had happened with that.  Books from a few years
back all kind of have that "May fly as soon as 1999" type wording...

Ok, so the -100X was stillborn and they're focusing on the -200/300 as
growth bases.  Makes sense.

Interesting hybrid.  They'd probably take out the 5th door then I
suppose.  Soudns like a -200 with the wing and wingbox of the -300.

I wonder how far the could push it.  They still aren't storing fuel
outboard of the wing-fold lines are they?  And they can also use the
horizontal stab too.  I'd love to see how far it could go using all of
the available fuel storage options.

(Of course I'd also like to see just ONE customer order folding wings -
just to see it used...)

Ok.  Blue skying.  I don't see the point in a larger stretch:
1. The -300 is the longest airliner already.  Making it longer could make
airport handling 'interesting'.
2. It'd compete with the 747-400, and possibly the -500/600 plans to some

Personally I was kind of surprised that they kept the MD-11 in production
beyond just filling existing orders.  You'd think the 777 would be the
pick of the litter to take that entire market.
