Bernoulli's Principle

This theory, which originally was applied to his research in fluids & medicine (particularly blood pressure), helps explain how planes fly.
He discovered that the principle that the pressure of a fluid decreases when its speed or velocity increase.
This helps to explain that when a plane is speeding up for take off, the faster it goes the less air pressure is exerted on it and therefore the plane is able to 'lift-off' the ground and fly. A plane that does not obtain sufficient speed on the ground, for its size & weight, may not be able to take off successfully

Ed's note: I am trying to find the co-relation between flying and perspiration
