minimum clean cwatters and Mechta
To me it looks like the CofG got in front of the centre of buoyancy. Possibly because of the fuel used up,as mc suggested. I'm guessing they must trim it by pumping gas into and out of multiple gas bags inside the envelope. So, I'd speculate the crash occurred because the trim mechanism failed, or pilot error, pumping gas the wrong way. Is it fbw?
Didn't see Mechta's last post. Does the Airlander certainly use ballonets? I would have thought it more practical to use pumps to transfer helium to a high pressure storage tank when reducing buoyancy.
