Thirteenth Iteration B

When I made these aircraft I actually made them in halves, so that A) I wasn't dealing with symmetry issues ( small tip: if you do this, make sure to make any curves that come to a peak in the middle tangent to a line that goes straight out at 270 degrees if vertical is 0 - otherwise you'll end up with a funny double bump in the middle when you mirror it), and B) so that I could easily place the objects with the most weight - in this case it's the engine, two pilots, and then baggage (I believe fuel was going to go in the wings).
