It got me thinking though... the paper plane seems like such a basic and easy concept. But, before they evented the aeroplane, did the paper plane exist??? surely not otherwise they would have worked out how to build a big plane, yet paper planes are so simple?
I wonder.. did Galileo or whoever invented the aeroplane (excuse my obvious ignorance/lack of knowledge) draw plans on paper then scrunch them up and throw them in the bin, or did they fold them into a plane and throw it in the bin?
