Amid talk of sustainable aviation fuel and electric flights, there's another form of air travel currently being mooted as a green alternative to flying: the airship.
The “hot air” part was nonsense. Most aircraft are painted white (to reduce radiative heating IIRC) so it’s not surprising that an airship would be white too.
Shouldn’t the balloon be black rather than white?

Probably not helpful with helium or hydrogen filled ones.
