I think we had some discussions last year when KLM and Airbus announced the project with sketches. Interesting to see a model flying - although I wish they had included the "rough landing."
Let's see. A
flying wing that is also a
slender-delta wing that is also a
cranked-delta wing that is also a
tailess delta that also has a big chunk missing out of the trailing edge.
Rather a mash-up of a B2 with a Concorde and a Draken - with a little Antoni Gaudi thrown in for the interior design....
I won't say "what could go wrong?" But it must have the pitch dynamics of an amphetamine-laced flying squirrel.
Anyway, I wish them well. Certainly inventive. Some design ideas explicated here:
