The world’s largest airplane, the Airbus A380, has a maximum weight of 1,200,000 lbf, wing area of 9100 ft2, wingspan of 262 ft, and CDo 5 0.026. When cruising at maximum weight at 35,000 ft, the four engines each provide 70,000 lbf of thrust. Assuming all lift and drag are due to the wing, estimate the cruise velocity, in mi/h.
