The problem is not manufacturing ...Boeing and Airbus can go up to 60 planes a month...the problem is if the suppliers can keep up with the rhythm, that is the culprit for the upcoming programs...
I knew it was somebodys fault other than Boeing and Airbus.
They would happily take the money but they couldn't deliver the airplane because the elves in the North pole and the Black forest couldn't produce it, That's the way of today's global economy some days nobody is going to buy your paper airplane.
