1.   Adler says his new disk design dampens this effect by dividing the airflow at the leading edge to reduce lift in front while increasing lift at the trailing edge.

2.   But at night the cool air chills the balloon gas, reducing its lift and forcing the balloon to descend.

3.   Excessive ice on wings reduces lift, sometimes to the point of causing a plane to crash.

4.   He reduced the lift in his front foot and found he could still drive the ball, as he explained through an interpreter the other day.

5.   Lift is reduced as forward speed declines.

6.   That turbulent flow of air puts more pressure on the wing, reducing lift.

7.   The relatively low density of hot air reduces aerodynamic lift.

8.   Aviation consultant Michael Boyd, president of The Boyd Group in Golden, Colo., said a small amount of ice could reduce the lift on a wing.
