27 March 2009, BBC News: Wind-powered car breaks record Citat: "...Richard Jenkins reached 126.1mph (202.9km/h) in his Greenbird car...The designers describe it as a "very high performance sailboat" but one that uses a solid wing, rather than a sail, to generate movement...the designers have added small wings to "stick" the car to the ground, in the same way Formula 1 cars do..."
NASA, Glenn Research Center: Bernoulli and NewtonArkiveret 7. februar 2006 hos Wayback Machine Citat: "...The integrated velocity variation around the object produces a net turning of the gas flow. From Newton's third law of motion, a turning action of the flow will result in a re-action (aerodynamic force) on the object. So both "Bernoulli" and "Newton" are correct. Integrating the effects of either the pressure or the velocity determines the aerodynamic force on an object..."
June 28, 1999, Science & Technology at Scientific American.com: Fly Like a Fly Citat: "...wing curvature seems to play almost no role in insect flight; the wings are surprisingly rigid and flat, Dickinson notes... the hover fly, appears to use delayed stall very little, but makes great use of rotation circulation and wake capture..."
