Boeing says plastic 737s not far off
Forget big metal birds of steel, the aircraft of the future will be constructed out of plastic.
That is according to American plane-maker Boeing who says new technology will soon enable us to take flights in carriers largely constructed from non-metal materials.
Alan Mulally, president and CEO of Boeing Commercial Airplanes, said the company was looking to replace existing 737 models with newer models made from materials called composites.
A composite is formed when two or more materials with very different properties are combined together. They are already used in items such as tennis rackets and bicycle spokes.
