@dw.science: Humans have dreamed of soaring through the air for thousands of years, but our bodies just aren’t built for unassisted flight. Birds have superlight skeletons made of fused or hollow bones, powerful flight muscles attached to a huge breastbone, an ultraefficient respiratory system, and wings covered in adjustable feathers that create lift and thrust. We’re simply too heavy, not strong enough, and lack the specialized anatomy needed to take off under our own power. We can still experience the sky, but need tech like wingsuits, gliders and jetpacks to do it. Author: Derrick Williams #STEMTok #learnontiktok #dwscience #WhyCantHumansFly #BirdFlight
