Friction between glass and air

Say that an airplane is going in 2000 km/h. On the side of the airplane, there is a 10x10 cm window. How much friction would this window cause? For the sake of the calculation, imagine that the airplane is infinitely long. The window is also perfectly level with the rest of the wall, and there is no turbulence on the side of the plane. The outside air is also standing perfectly still. The temperature is 25 degrees celsius. The airplane is travelling at sea level. Please reference everything. Also. if you are making any assumptions, you need to state them. If you can provide calculations in excel, it is the best, because I can then follow and control your calculation. It might go a week before I accept your result, so I can can check it properly. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
