Suppose a supersonic airplane flies at a speed of 1670 km/hr from Nairobi, Kenya to Quito, Ecuador; note that this is the same speed that Earth rotates, but in the opposite direction. Describe how this flight would look to an observer on the Moon.
What will be an ideal response?
Answer: The airplane would essentially appear to lift straight off the ground and then remain stationary while Earth rotated. The rotation would carry Nairobi away from the airplane and Quito toward it. When Quito arrived, the airplane would drop back down to the ground, completing the trip.
