It's difficult to see any rational business case for Airlander. They've done little to address the Achilles Heel of all large airships - they are highly vulnerable to severe weather and need a large and expensive "safe harbor" that they can retreat to when things turn nasty. This requirement is completely contrary to the stated commercial purpose of providing heavy lift capability in remote locations - where any sort of potential safe harbor is likely to be days away if the weather unexpectedly turns.
Large airships are and will remain a commercial dead end unless someone can figure out a way to address their vulnerability to severe weather.
