eli5: Why is it not possible to build bird-like attachable wings that account for body proportions to allow humans to fly or glide around?
In: 2102
it is possible, its called a hang glider.
the wing just needs to be massive and cant be attached to our arms because no human has the chest muscles strong enough to flap them
were just too heavy and weak to have “bird like” wings
The primary answer is pectoral muscles.
To propel a human-weighted person to flight, you would need immense pecs. Last I heard, you would need something like G sized boobs, except pure muscle, with all the relevant anatomy to match (bones, sinew etc.)

Birdies small
humans fatty fatty no fly
