    Aeroplane. The "plane" is the giveaway. But hovercraft and coanda craft wouldn't fit.

    Or autogyros.

    The blades are wings that use a weird condition to get lift from the Bernoulli effect. It's still a "rotary wing" vehicle.

    ...but it's not called an "aeroplane/airplane". It's an autogyro.

    Yah, she's been around a while... easy on the eyes and ears and very adventurous. Seems to fly pretty well too... or at least, she's still alive!

    I prefer Newton to Bernoulli anyway. There's a lot of hand-waving about "equal transit time" and such that fails to explain why fighter jets can fly inverted and generate lift or why symmetrically shaped wings can generate lift-. "Angle of attack" is much more satisfying to me.

    Or, as many have put it--you can make a brick fly with a big enough engine.

    Yes, I didn't want to confuse the penetrating clarity of the argument, but some wings work more by reaction than Bernoulli effect. It seems to be a bit of both in general.

    I still don't think of floating as flying.

    Wow! I knew that they were capable of fucking you good and proper, but when did THAT happen?

    Makes me wonder if there are/were any aircraft that used a combination of both, since a large amount of energy on a conventional craft goes toward generating lift.

    When I was learning to read, one of the stories was about a child and his family crossing the Atlantic in a dirigible. What I recall were the accommodations--sort of a cruise ship in the air. Sad that we've lost that idea and are willing to get crammed into flying cans to get somewhere fast.

    Life is longer today, yet we feel as if we have to live it faster.

    Rarity of Helium doesn't help and as we stop pumping up natural gas we will have even less.

    They are designed to in fact destroy life.

    Could they have been designed to in fiction destroy life? Just watch those split infinitives, right!?

    They add piquancy.
