Perhaps the welcome that we appreciated most was that given us next day when, at the Weybridge works of the Vickers Company, we were cheered and cheered by the men and girls who had built our transatlantic craft. We were glad indeed to be able to tell them and the designer of the machine that their handiwork had stood a difficult test magnificently, as had the Rolls-Royce engines. One of my most sincere reasons for satisfaction was that the late Mr. Albert Vickers, one of the founders of the great firm, regarded the flights as having maintained the Vickers tradition of efficiency, originality and good workmanship. That Lieutenant-Commander Read, U.S.N., who commanded the American flying boat _N. C. 4_ in its flight from America to England, had left London before our arrival was a cause of real regret. Both Alcock and I were anxious to meet him and his crew, so that we might compare our respective experiences of aërial navigation and of weather conditions over the Atlantic. The United States aviators who flew to Europe, and those that were so unlucky in coming to grief at the Azores, showed themselves to be real sportsmen; and without any exception, there was the best possible feeling between them and all the British aviators who made, or attempted to make, a non-stop journey from Newfoundland to Ireland. Although I am supremely glad to have had the opportunity of flying the Atlantic by aëroplane, afterthoughts on the risks and chances taken have convinced me that, while our own effort may have been useful as a pioneer demonstration, single or twin engine aircraft are altogether unsuitable for trans-ocean voyages. We were successful--yes. But a temporary failure of either of our motors (although this is unlikely when dealing with Rolls-Royce or other first-class aëro motors) would have meant certain disaster and likely death. Another vital drawback of the smaller machines is that so much space, and so much disposable lift, is needed for fuel that the number of persons on board must be limited to two, or in some cases three, and no freight can be taken. Yet another is that should the navigator of an aëroplane make an important error in calculation while flying over the ocean in fog or mist, an enforced descent into the water, after the limited quantity of fuel has been expended over a wrong course, is more than possible. In the present condition of practical aëronautics, the only heavier-than-air craft likely to be suitable for flying the Atlantic are the large flying boats now being built by various aircraft companies; and even they are limited as to size by certain definite formulæ. The development in the near future of long flights over the ocean would seem, therefore, to be confined to lighter-than-air craft.
