2) How did aviation start? pg1
With aircraft made up of mainly one wing, materials that were used were strong enough to bear the lift charge.
With aircraft made up of two wings in order to distribute the lift charge, inasmuch as materials that were used were not strong enough to bear the charge in only one wing.
By using semi-monocoque structures.
