As Tom said, the added weight, cost, complexity, etc. is not worth it. The only gain is less drag, and here I have to disagree with other posters, this is always highly desirable.

RE: Airliner Kinetic Warming Of Atmosphere

Let's see if I have this correct: all drag will dissipate into heat, heat that will increase the temperature of the fluid. A very common value in cruise for an airliner is L/D=18, thus taking a weight of 0.8*MTOW for a 744 yields to a drag of D = 174 kN. With a speed of 250 m/s, this gives a power o...
