    I think flying is just moving through the air. A stone flies if I throw it, right?

    Or a flight of stairs?

    Does a rocket fly? It doesn't employ the Bernoulli effect.

    Only in a metaphorical sense. It follows a ballistic trajectory, energy losses ignored.

    Or is this poetry we are talking about?

    Do stairs fly?

    Oh. I see that Asterix and I are making opposite points with the same example.

    Merriam Webster's first definition, which corresponds to the rational engineering sense

    To move through the air by means of wings or winglike parts.

    They also list some poetic, metaphorical, airy-fairy secondary meanings.

    What about the Canadian Coanda flying saucer?

    Didn't have wings or winglets it used the Coanda effect.

    So rockets (and missiles in general) don't fly. So when you're hit by a cannonball flying through the air, it isn't flying.

    Which depends on Bernoulli effect.

    Then there's the old adage, "Anything will fly if you throw it hard enough."

    Emirates gives its modern form: "Anything can fly if you spend enough money on it."

    Merriam-Webster allows it. I say it is unworthy.

    Is a rocket flying when operating in the absence of air?

    Just struggling to point out, in my own inept way, that there are differences in common and scientific speech.

    But I'm unaware of a commonly-used scientific term for a vehicle or projectile that owes its lift from the Bernoulli effect.
