OK, this is from a children's website, so I'm addressing the right audience.
"The secret to the helicopter’s flight is the rotor, which is the pair or group spinning blades on top of the helicopter.
They are angled, like the blades of a ceiling fan.
As they spin and cut through the air, they push the air downward which causes the opposite reaction in the helicopter. It goes up!
No air, no fly.

Ummm...no.

Only rocket propulsion is effective in the vacuum of space...

Dead giveaway when someone is talking out of their a$$ and really doesn't know the answer to a question is when they say stuff like "try again" over and over again instead of providing the answer (that they don't know, or think they might know, but are afraid they might be wrong or only partially correct).

That's why you don't see anyone being rescued by helicopter in the Himalayas.

It is about this simple.

No, that's because the weather in the Himalayas can turn bad in a few minutes, causing your solar-powered helicopter to lose power and crash. Too dangerous.

Actually, no, it is NOT "about this simple". Listen up friend, when the next generation of moonships appear and low and behold, they are solar powered helicopters...man oh man, you are going to look like a fool. Tell the truth, do you even understand what a vacuum is? A vacuum is teaming with sub-atomic particles constantly flashing in and out of existence. And mark my words, this bubbling froth of nothingness IS enough to provide lift for a whirlybird.

Really? OK, let's test your theory, shall we?

Helicopters get lift by means of their blades acting in the same manner as airplane wings. The top surface is curved, while their bottom surface is flat. This results in air moving over the blades having to move a greater distance than the air beneath the blade. As a result, less air pressure is on top of the wing. This higher pressure underneath the blade pushes the blade (and hence the helicopter) up.

Really dude, you might want to raise your game before talking out of your ass again.
Wait, is this helicopter on a treadmill or some shit?

You've got it! All you'd have to do is bring some atmosphere with you, releasing it near the blades as you fly through space. Problem solved.

You missed the point.
You guys are all totally forgetting about dark matter! The space between here and the moon is filthy with the stuff. You just need to start whirlpooling that dark matter around and it will suck the helicopter right up to the moon! The real problem is the landing!!

If it actually exists.

What the heck are you talking about? Ummm...ever turn out the lights in the middle of the night?

Landing should be easy. Cream cheese is soft. Might get the landing gear stuck though.
Unless it's made of parmesan, of course. That'd hurt.
I'm sure Wallace and Grommit made a documentary about the cheese thing a while back...

But it's only there when it's dark. So this would never work except during a lunar eclipse when there is a corridor of dark between the earth and moon.
If you couldn't make it to the moon with a traditional helicoptor, how high up could you actually make it into the earth's atmosphere?
Would you even make it out of the troposphere? Because if the air gets too thin that high up, there isn't enough for the blades to push off against. I am thinking the difference between swimming in molasses or water.
