WHY CAN'T HUMAN FLY ? ( COLLINS BIG CAT INFORM ) WHITE BAND 10 Dry Pencils making them ideal for studentsHumans cannot fly because their bodies are too heavy, their bones are too dense and they lack of necessary muscle strength and wings surface area to generate enough lift to overcome gravity. Unlike birds with hollow bones and specialized wings, human anatomy is not designed for flight, making us too heavy relative to our surface area. BY : SARAH FLEMING WES LOWE
