On the instigation of Dr. Hermann Köhl, the successful German ocean flyer, Mr. Lippisch, the chief engineer of the Rhon-Rossiten Association, and his staff have developed a tailless airplane, which has so far shown excellent flying qualities. It was recently demonstrated at Berlin-Tempelhof airport before a party of prominent people interested in aviation and representatives of the press. Dr. Hermann Köhl, as he said in a speech, sees in the development of this type of airplane the present most promising step towards achieving more economical airplanes, capable of profitable long-distance transport work across oceans and continents. He is personally interested in the early perfection of such airplanes, with which, as we know from other sources, he plans inaugurating a regular transport service between Europe and America. (...)
In the hands of the pilot Groenhoff, the airplane showed a surprising degree of maneuverability. Groenhoff said the airplane steers very lightly, and he can do anything with it which he can do with any good normal airplane, including looping. The latter were, however, not shown at the demonstration. The airplane flow very close circles and zoomed up in a manner that would appear to indicate its having plenty of reserve power. It seemed practically nonstallable.
