they can, these are called lifting body aircraft. They maintain directional stability using the control surfaces near the tail.
Explanation:
Humans are not physically designed to fly. We cannot create enough lift to overcome the force of gravity (or our weight). ... Their light frame and hollow bones make it easier to counteract gravity. Air sacs inside their bodies make birds lighter, which enables smoother motion through air.
