Why can't humans fly?

Jade and Lauren want to know if it's genetically possible to grow wings on your back and fly. Find out from MIT aeronautics and astronautics professor, Dr. Jaime Peraire!

The crazy thing is, this video was not recommended to me. I actively looked for this.

We can't fly because no one believes we can can fly.

Well i can always fly in my dreams at night... :(

[nazairking]

I believe man can fly, we just don’t know it yet ‼️

Instructions unclear: I started eating my own weight daily and now I'm a diabetic fatso with no toes

My opinion is stupid.

Question: Why humans can't fly?
My answer: because humans often gained weight and to heavy to lift themself.

Quite stupid.

Then how come some dinosaurs were able to fly? Pterodactyl

The only way you can fly is if you actually believe you can

What about prosthetic wings? Adding a new pair of limbs to the back.

Anti-gravity/flying saucer technology made more small would make it so the human body can fly.

i was expecting more comments on this video

So does this mean that if we managed to create artificial wings (probably using the steel-like graphene material made by MIT themselves) with a span good enough to balance the human body weight, we could actually fly ? Also, if a person weighs 60kg, does an 8m wingspan suffice ? (if compared to the albatross example)

TONY STARK WAS ABLE TO BUILD A FLYING SUIT IN A CAVE!! WITH A BUNCH OF SCRAPS!!

It would be pretty hard to fly with a pair of wings on your back. You'd probably be pretty top-heavy, or your arms would probably have to be disproportionately weak so they're not a lot of dead weight. You'd also probably have to be stretched taller, and have a massive membranous webbing going from your wings' fingers down to your toes, so clothing would be kinda difficult.
I wonder how that would all be on your spine and knees, unless the wings r so long you use em like crutches.

I want to Fly so bad.. I want Powers :<

“Hey, can people fly?”

“That’s a shame.”

On a short notice, we would need to eat less than he made it seem, because smaller animals like bats have a way higher metabolic rate. Small Mice also eat approximatly double their bodyweight and do not fly. The bigger the animal, the less it has to eat compared to its bodysize because bigger animals have less surface to lose energy over compared to their volume.

Why not create a small motor that would make the wings to sway

What if an infant had wings? Or a young child. If they weighed as much as a large bird with the exact same wingspand could they fly?
