From the BBC article, a quote from a 'high profile' investor, Iron Maiden's lead singer, Bruce Dickinson
It is 70% greener than a cargo plane, he says. It doesn't need a runway, just two crew. And it can plonk 50 tonnes anywhere in the world you like, which is 50 times more than a helicopter.
(My bold)
I'd like to see you 'plonk' it at Combat Outpost Zerok, of Restrepo fame, let's see how it holds up to a hot LZ @ 7000' surrounded by mountains, in an Afghan winter.
A ridiculous claim that would make even Snake oil salesmen blush.
