I'm so glad I lost that "You can't fly a helicopter in Mars atmosphere" bet.

    Well, they've tested it in mars equivalent atmosphere and gravity (through the clever use of pulleys) soooo, hasn't he? he didn't bet you couldn't fly a helicopter on /mars/, just it's atmosphere.

      I think it's fairly well established you can. The problem is about whether we will.
