Easy to tell it's H-powered ... look at all the water vapour it's left behind! ;-o)

.... where you learn it is an 18M wingspan. Hydrogen aircraft have flown before, but I don't
know if any used liquid hydrogen. I did see recently that Toyota is offering the hydrogen

because energy density is not critical, as it is for airplanes.
