I don't think that anyone has mentioned the fact that the slower you go, the less effective the controls are going to be. You end up with zero control at zero speed, and have to rely on the vectored thrust from the engines. Do they rotate to the extent that there is no thrust in a horizontal direction?
Another thought is that the Airlander might have huge problems with centre of pressure travel. Put that alongside controls of limited effect, and some odd attitudes might result.
Especially on landing.
