Many of you have been at pains to state this is not 'lighter than air' aviation.
Come on Leon, 'lighter than air' is the term given to this class of aviation and not some cynical attempt by HAV to hoodwink its investors, as you imply (though what
advantage they might gain from claiming their vehicle actually is lighter than air, I'm not sure).
Furthermore, both company brochures state the flying endurance is a number of days and not weeks as stated in crowd sourcing.
Well, given as they are
currently touting the Airlander as a manned platform for the commercial sector it is something of a moot point whether its endurance can be measured in days or weeks. I guess it will be up to the MoD to assess its true capabilities once they come to evaluate it for military applications, if they do.
There is no proof that it can fly from the sea as yet - that might be an aspiration.
Indeed, but the same can be said for any claim made for any other aircraft that ever flew - nothing is proven until it does it for the first time. Is that a reason to wish for its failure?
