That's the point. Successful commercial aircraft also have input from Marketing (hopefully telling you what Southwest and Passengers actually want), Finance (telling you if that feature is actually worth the cost/effort), and QA (telling you if that feature will actually be reliable).
So yes, a commercial aircraft only being designed by aeronautical engineers would be a failure, IMO. And that is the problem that faces Open Source projects today.
