Hi Stilton.
A Porsche 911 handles different from a Ferrari, but that doesn't mean one has a design problem over the other.
MD11 is certified to same requirement as other aircraft (Lockheed, Boeing...etc...) and does this well.
A fairly large amount of MD11 have gone upside down. You cannot land the MD11 with the same technique as you would in say a Boeing 744, and in this particular area the MD11 differs from other. But that is not design flaw.
If this is not understood and trained, then you will pay as number one on checkout to St. Peter.
A 747 cannot roll much into the wind during a crosswind landing, because the outer engines would hit the ground. This is not a design flaw, but the natural effect of the aircraft design. If this is not understood by the pilot = kabummm!
