Getting heavy planes off the ground requires more power than flying them straightaway. Hence, attempts to shove them upward from inclined planes; hence, the device of the German Dr. Hugo Junkers, which last week's despatches reported successful. He places the plane which is to fly, on the wings of a large three-motored auxiliary plane. The auxiliary leaves the ground with its load, when good flying height is attained, the top ship takes off from the auxiliary, which returns to its field. Last week the U. S. gave Dr. Junkers letters patent for his idea.
