Play in free flight mode with a fast jet. Flip on the afterburners and fly up at a 45 degree angle. Get up to about 47,000 ft. When you get up to 1120 mph, do a vertical nose dive with the afterburners still on. Continue in the dive until you get down to 15,000 feet and level off. If you got your speed up to at least 1375 mph, switch the view to behind the plane and fire a missile. If you are flying fast enough, you should see the missile flying along side your plane.
