Airbus is known for its huge passenger jets, but it has just debuted something out of the ordinary at the Paris Air Show. Airbus unveiled the E-Fan 2.0 prototype aircraft. It's an all-electric aircraft that claims to be the first "plug-in plane". It's a small, two-seater plane with a 31-foot wingspan. The plane is crafted from carbon fiber composite materials, keeping the aircraft light, weight only 1100lbs when empty.
