Method for creating a bulge in a fuselage What method would you suggest I use to create, as best I can describe it, the "bulge" or streamlined c-shape add-on found under some commercial aircraft (see the underside of an Airbus A320, or a Citation Latitude as examples) 

I have the fuselage (cylinder) modeled, and am now stuck at how to go about adding this c-shaped bulge under and attached to the the fuselage with its well-defined crease along the top where it meets the round-face of the tapering (to the rear) fuselage, and then its gets a streamlined shape at the bottom, front, and back. I have the aircraft's blueprints, so I know its size, location, dimensions, etc. but the method for adding this is my stumbling block for now.

I've added a couple of images to show what the end result should look like, so hope that helps.

What's the best method and tools you'd suggest I use in Blender to get this done? 
(I have both v2.7 and the 2.8 beta -- so can use suggestions for either version)

Thanks for the help!
Hard to do it without a complete blueprint, but I guess you can do it this way:


Create the right view profile, which is basically an extruded cylinder.
Draw the wing cut with the knife.
Extrude the wing, use all the views to make it correctly.
