No, the tailwind doesn't get you there. But it will help the airplane during flight by pushing it forward, especially a Boeing 747, In principle, the captain and his crew command the take off and landing. Once in flight, the auto pilot basically flies the aircraft. The plane's instrumentation computer calculates the head wind or tailwind speed based on the data collected, then set the auto pilot to fly at its optimum cruising speed. This is done mainly to save fuel. A Boeing 747 flying from SFO to HKG typically takes 13.5 hours covering 6900 miles, that translates to an average air speed of 511 miles/ hour.  On the other hand, the same flight from HKG to SFO will only take 11 hours which translates to 627 miles/ hour. The flight is typically smoother and faster for the passangers because of tailwind. But the fuel saved on the 2.5 hour flight translates into thousands of dollars in profits.
