Apparently, you want to model the wings.

I'd start with that cylinder, but apply some uneven scaling. It could be 
something like :
cylinder{End1, End2, 1 scale<5,1,1>}

A larger value will result in flatter top and bottom parts.

Another option would be to use a prism for the wings. Then, it's just a 
question of choosing the interpolation method that work best for your 
needs. Try the bicubic spline. Maybe more cumbersome, but, you'll need 
only one object for the whole wing.
