Wright Brothers

Description:

"What the scientists say: The shape of an aerofoil creates an upward force called lift. An aircraft's pitch changes when its nose rises or falls. The same forces act on all aeroplanes - weight, lift, thrust and drag. The first powered flight was made on 17th December, 1903."--from back cover.
