Ready to take the skies is the North American X-15 Plush! Inspired by the North American X-15 rocket-powered research aircraft that bridged the gap between manned flight within the atmosphere and manned flight beyond the atmosphere into space. After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6. Made from premium materials, this plush makes for the perfect gift for just about any occasion.
