Do you mean more massive than a normal helicopter? Why? The article seems to state that the newly available technologies made their new helicopter lighter than before.
Heh. I see I was down-modded, which wasn't very surprising. I was trying for exactly the kind of pun/humor that I know HN doesn't appreciate.
ObJokeExplanation: For me, the wording of the title was misleading in a funny way, since helicopters generally don't break speed records while literally on Earth.
HN does sometimes appreciate that, but you have to lead a bit. Maybe if you'd quoted the title immediately before your response, since most people will have read one or more other comments (and maybe the article itself... shocking, I know) before reading your comment. The headline has expired out of memory at this point. That's my excuse for why I didn't get it.
