FLIGHT APRIL 26TH, 1945 ing-off " near the ground, the result may well be fatal. All this leads to the thought that perhaps the stall indicator ought to be revived. Our good friends in America appear to think so. The Civil Aeronautics Authority has sponsored a development programme, and one scheme, the C.A.A.-Gurley, is well advanced and likely to be on the market soon. It is based on the simple vane which was used in the British Savage- Bramson anti-stall gear produced in this country soon after the first world war, but is reduced to the simple function of merely giving visual and aural warning. Mr. Bramson's invention went much farther in that it prevented the stall by automatically operating the eleva- tor control when the angle of incidence of the wing reached a predetermined value. Aircraft or Battleships ?R ECENT events have made it inevitable that com- parisons should be drawn between the effectiveness of seaborne and airborne weapons of war. No one would suggest that air power has completely replaced sea power, any more than that it has rendered armies superfluous. A correspondent takes us to task for our editorial comment in the April 12th issue. We have jead that comment again, and it appears to us that our correspondent has quite missed the point, which was merely that the R.A.F. has, by its work in this war, earned, the right to be treated as the equal of the other two Services, and that it must never again be starved of funds while the Navy is allowed to spend millions on battleships. The "stale and outmoded controversy," which our correspondent accuses us of having revived, has, we think he will agree, been rendered rather less outmoded through the sinking, since he wrote his letter, of the AN R.A.F. HELICOPTER BRANCH : The Royal Air Force now has a school for training helicopter pilots. Here an instructor is seen giving a demonstration on a Sikorsky R4B of an evolution which is not recommended for beginners. Other pictures issued show five of these machines flying in echelon. Presumably that proves their manoeuvra- bility and that they can be flown accurately. The same may be said of the evolution in this photograph, but apart from the skill required in piloting, a serious drawback is the high sinking speed when the rotor is autorotating CONTENTS The Outlook War in the Air - - - - - Here and There - - - - Recce Wjng - - - Civil Aviation News - Australian Liberator O.T.U. - Our Future in the Air ...

These recent sinkings have occurred while the vessels were stationary. In his review of the situation Lt. Cdr. Hurren surveys the history and actual events of the bomb versus battleship controversy, which include bth '' stationary'' and '' moving''. sinkings. Lt. Cdr. Hurren refers to the airborne torpedo as "by far the most dangerous of all present naval weapons." We assume that this is not to be taken as an indication that he belittles the .value of the new 12,000 lb. and 22,000 lb. bombs, but that these are R.A.F. and not naval weapons. It appears obvious that torpedoes could not have been used in the recent attacks on Kiel and Swinemiinde, and that therefore the heavy bomb also has an important part to play. The main thing is that it has been amply proved that aircraft can sink battleships, and for losses in men and aircraft which are relatively insignificant. Moreover, the limits of the battleship are within sight. Aircraft destructive power is only just beginning.
