this tells you barely anything......

0:35 Ton of metal? That's more likely 300kg of fiber glass.

@Bra23we12 that's true i kinda ranted...

@surfingcali69 unfortunately it's kinda wrong... look at my comment :(

"It produces an equal and opposite force so the helicopter goes up." hahahahahaha where were you in physics class?? ha when forces are equal an object is in equilibrium and does not accelerate. F=MA. The ground always applies equal and opposite force to anything standing on it and things don't go flying up into the air! And it's actually the curve in the rotor blade that generates lift via bernoulli equation with pressure and energies... I know this much from solo in C-150 Plane n 1 semestr phys

"how to get up in de air, what keeps you dere, what happens when engine shut off" LMAO of this womans Ignorance,. IT IS ALL THE SAME SHIT. ACTION AND reaction, being it you lady walking with you r little legs, bee it a tiny fish pushing th water back wards, being a squid pushing water through his ass to move forward, being it a heli or plane that displace air to move

[loswichitangeles]

I have an urge to learn how to fly helicopters!!!!

Airfoil, not Arafoil

I haven't read the previous posts...but I guess I'm not the first who wants to pick holes in the theory described.

Enough to say that this really isn't what keeps a helicopter in the air.....on the other hand.....it's meant for entertainment and not meant to be informative or definitive.....so I'll shut up.
