@Hypx You are telling me this is a practical aircraft that can reliably carry goods or passengers 1000 km and be turned around (i. e. refueled with hydrogen) quickly? What is flying (perhaps, see below) is a technology demonstrator.
This is like saying the Boom supersonic airliner is already flying, when in reality only a tiny technology demonstrator has been flown. Once, at low speeds and with the gear down. The Boom Overture supersonic airliner is, and remains, vaporware. It is telling that most pictures of the AMSL Aero are CGI, and I cannot find any video of a flight.
EDIT: the only picture showing "flight testing" is a still image showing a tethered hover. I'm not impressed.
