In 1899, Scottish American engineer Alexander Graham Bell, the man best known as the inventor of the telephone, began investigating the possibility of powered flight. To wit:

Inspired by the box kites of Australian [aeronautical pioneer] Laurence Hargrave, Bell began to multiply the lift-providing cells, creating compound structures of multiple kites.The basic problem of creating flying objects is that as a body’s surface area is squared, its weight is cubed, limiting the maximum size and lifting capability. Over the course of years experimenting at his Nova Scotia laboratory, Bell discovered that a tetrahedron — a three-dimensional prism of four triangular sides — could be useful.

    “as a body’s surface area is squared, its weight is cubed,”

    Is this true if the body is essentially a two dimensional sheet of fabric?

    Kites were simultaneously invented over two thousand years ago in China and Indonesia. They had recreational and military uses.

        The human race in all its ethnicities on every continent has shown a propensity towards cruelty.
