The desire to fly is as old as human culture. Ancient Egyptians studied birds in an attempt to learn how to fly. Centuries later, we were still strapping on wings, jumping off cliffs… and crashing. It took a bit of time, bruised bodies and the occasional death to figure out that we were too heavy and too weak to propel ourselves with flapping wings. But in the last century, our dreams of flight finally became reality. While we haven’t grown wings, we have learned how to fly by shaping metal and plastic into machines that take us higher and faster than birds could ever fly or possibly even imagine.
