Thus, may be sum- marised this year's race for the chal- lenge cup presented by His Majesty the King, which was flown from Hendon, on July 9 and 10. On the face of it the figures are somewhat disappointing, and if one were to judge the reliability of British aero engines purely on the basis of the percentage of machines which completed the 1,464 miles (some 35 per cent, only) a rather alarming picture might be Race presented. Fortunately, when one comes to look into the matter a little more closely, there is no need to feel unduly alarmed, nor to jump to the conclusion that British aero engines are not uniformly capable of prolonged running at full throttle under conditions such as obtained in the King's Cup Race. To begin with the non-starters, we gather that Leslie's Hamilton's engine was not ready in time for the race, and thus one entrant was eliminated. The only other non-starter, Mr. Watt, was not per- mitted to take part in the race because it was dis- covered, somewhat late, that his engine was a French Clerget, while the rules of the King's Cup Race stipulate that the aircraft and engines must be entirely built within the British Empire. This, therefore, accounts for the two non-starters in the race. As regards those competitors who did not finish the course, it may be said in general that the causes of their retirement were of a trifling character, yet the effect was, of course, the same as if they had, one and all, suffered from serious engine trouble. The old saying that a chain is only as strong as its weakest link is nowhere more true than in relation to aero engines and their installation, and 1,464 miles at full throttle—perhaps in some instances at engine speeds rather higher than those advocated by the makers—is a very severe test of any engine, t par- ticularly, of course, in the case of engines fitted in the slower machines, which have to run for longer periods
