"This very technical program explains the principles of flight as achieved through lift, force, thrust, and the interactions between air pressure and wing design. Each concept can be used alone, or together, for classroom investigations, problem solving, and discussions and applications of the basic mathematical formulas involved. The information is also useful in the teaching of physical science, aerodynamics, mechanics, or the properties of matter."@en . . "Why planes fly and other things"@en . . . .
