IF you think the Hindenburg crash was sensational, wait til one of these things filled with hydrogen crashes!
The John Sharp, NXT design was developed in CA. Prototyped in Mojave Airport and tested before moving to the Reno test. John retired the Nemesis to the Smithsonian and has since done the same with his NXT. He needed a production number of sorts I believe it was to be at least 9 aircraft to be considered a manufacturer. He sold them all except for his own. The NXT was a side-by-side two seater (staggered) so to keep the fuselage narrowed as much as possible. I was working for the FAA at the time when John came in for the airworthiness inspection after inspection I issued his Experimental certificates of the years.
And then there’s the only slightly inconvenient fact that the production of hydrogen consumes more energy than may be recovered from the end product. Countered only by the saving fact that the problem itself is the entirely-fraudulent Fifteen Trillion Dollar product of the fascist-Marxist Mann-made-GW Industrial Complex. And that we have sufficient mineral fuel resources to keep us cracking along for several thousand more years.
