Hi Greg.

Are you going to build this next generation KR2S or should I say KR2NG (aka
B737NG)?

I'd consider changing the shape of your aft upper deck design as it will
likely create an area of negative pressure and air flow separation.  This in
turn creates drag.  From what I have read, the current KR2S aft upper deck
is near perfect in terms of drag minimization.

Have fun with it.

Cheers
