A commercial aircraft flying horizontally at 500 mi/hr encounters a heavy downpour of rain falling vertically at the rate of 20 ft/sec with an intensity equivalent to an accumulation of 1 in./hr on the ground. The upper surface area of the aircraft projected onto the horizontal plane is 2960 ft². Calculate the negligible downward force F of the rain on the aircraft.
