Rotors yes, fans no. You have to articulate the blades and control them in their individual pitch axes through a swashplate. And they have to be bigger in diameter, and controlled by a highly skilled pilot.

Because generating lift on a fuselage is throwing energy away. A fuselage -- any fuselage -- has a very low aspect ratio, and its induced drag (that's the drag penalty occurred specifically because you're generating lift) is inversely proportional to the aspect ratio. Lift belongs on the wing.
Incidentally, this effect is where the expression "going ballistic" comes from. If you pitch an airplane nose-down enough to make the lift go to zero -- which puts you in a ballistic trajectory -- the induced drag goes away and you get a short-term increase in speed. (Of course you can't keep that up very long because it also puts you in a dive.)
...like exposing Q?
I believe this event is described as the closest complete miss. The 1972 event wouldn't qualify, even if it did exit the atmosphere.
It's a clumsy way of saying it has enough mass to have enough gravity that a spacecraft can achieve an orbit around it.
Well, it did some gatekeeping recently when it shut down r/thedonald for excessive scumbaggitude...could be payback.
When you're interacting with more than a couple of people, you are on television. And that isn't counting your body cam, so don't bother turning it off.
IIRC the pattern of blast damage on the ground was accurately circular, with trees felled in a radial pattern. I'd think a horizontally moving shock wave would leave a distinctive trail.
...in a world where the media think "exponentially" means "a whole shitload"?
Absolutely right; the quality of home video today frankly makes the theater obsolete. I have food at grocery store prices; I can have a drink; I can have a joint; if I want to go to the john I have a pause button; my chair is comfy and my feet don't stick to the floor; and if I hate the movie I can turn my chair around, put on headphones and do something else on the computer without spoiling my wife's pleasure.
Movie theater? The screen's bigger. BFD.
Don't you think there's something Huxleyan about that logic? Why make the language smaller, changing the meaning of an existing word when you already have perfectly good ones?
Yeah, I bitch about "blueprint", too.
Shouldn't it be selenologic?
At a job interview:
-Why do you want to leave your present job?
-They want me to become a COBOL programmer.
-So, you don't like to learn new things?
Let's see, where did I put that picture of a bear in the woods...
In a flight to 5000 feet, flat-earth assumptions are too close to even find the rounding error. But assuming you understand rocket design...that's a bit different.
