There exist humans on a world with 35% the gravity of Earth and air five times denser. These people have invented wingsuits with extensions that go past their arms and enable them to fly by flapping their arms.

In the same way that certain body types make people better suited for particular sports (e.g. thin people with long legs tend to be good runners), what would the ideal body type be for someone who flies with a wingsuit?

I am looking for body proportions, physical size, musculature, etc. Examples are encouraged.

  • $\begingroup$ So, you're kinda looking for a human that looks most like a flying squirrel? Bear in mind that examples of human musculature, etc., best suited for flying-squirrel status might not exist. $\endgroup$ Mar 9 '19 at 19:31

The flying fox is the obvious template. As you can see, the proportions are already reasonably close to human. Maybe shorten and narrow the trunk and the legs and make the shoulders more powerful.

The very long spidery arms and fingers will optimize wing surface area in the flight suit. This body has enormous pectoral flight muscles too, for awesome flapping. The rest of the tiny body minimizes weight.

I was not given a good explanation for how the detachable head improves flying ability but I am sure there is one.

  • $\begingroup$ And what of the explanation for the generously proportioned mammary glands? Bags containing lighter than air gases? $\endgroup$

    $\begingroup$ @Angelpray Mammary glands?! Where is your mind? Those are the aforementioned enormous pectoral flight muscles. $\endgroup$

Wings keep you afloat due to lift, which is proportional to area. Gravity pulls you down through weight, which depends on mass; for a fixed density and for practical purposes, it relates to volume.

And this is where the square-cube law gives midgets an advantage. As height decreases, surface area (both the midget's and the wingsuit's) decreases, but weight decreases much faster, providing a better surface-to-weight ratio.

Ultimately evolution would ravor pixie-sized humanoids if given time and pressure.
