Some planes are simple, such as one of the oringinal Wright Flyers, shown here, but this is also the start of a new era, where people took flight.
Eventually the Wright Brothers, mostly Orville because Wilbur died at a young age, perfected their plane to be in use for war.
Now 100 years later we can break the sound barrier and fly in formation, a feat that could not be accomplished if there was no advancement from the original Wright Flyer.
Now we can control hobby grade drones and fly them using transmitters, without the need of someone inside the plane.
Professional drone pilots can now take stunning aerial photography, a field that has just emerged in aerospace engineering.
