I'm sure I'm not the only person thinking this. The real headline is truthful but the HN "Hydrogen-powered aircraft has first commercial order" is a little misleading because it could imply that hydrogen powered aircraft are a new thing. We've famously [0] had hydrogen powered aircraft a century ago.
And while I'm on the topic of imperfect word choice, the company name is ASML Aero? There is already an ASML so I hope that Aero attached!
