The Schneider Trophy was Britain&rsquo;s to keep, and the contest was over forever.<\/p><p>Sixteen days later, on 29 September, Flight Lieutenant George Stainforth took another S.6B and pushed it to 407.5 mph &mdash; the first time any aircraft had exceeded 400 miles per hour. It was a staggering number for 1931, and it was made possible by the brutal, accelerated engineering the race demanded.<\/p>\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=1623668513  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/3\/32\/Rolls-Royce_R_and_Supermarine_S_6B.jpg\" alt=\"The Rolls-Royce R engine alongside the Supermarine S.6B\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">The Rolls-Royce &ldquo;R&rdquo; engine that powered the S.6B.

To win it, Rolls-Royce had to wring unheard-of power from its &ldquo;R&rdquo; engine, pioneering sodium-cooled valves and spark plugs that could survive enormous boost. Those hard-won lessons were poured straight into the company&rsquo;s next design: the Merlin.<\/p>\n<div style=\"background:#f8f9fa;border-left:4px solid #5C91FF;padding:20px 22px;margin:18px 0 24px;border-radius:0 8px 8px 0;font-size:16px;line-height:1.7;display:flex;gap:20px;align-items:flex-start\"><div><em>&ldquo;It is not too much to say that research for the Schneider Trophy contest over the past two years is what our aero-engine department would otherwise have taken six to 10 years to learn.&rdquo;<\/em><div style=\"margin-top:10px;font-size:14px;color:#555\"><strong>Arthur Sidgreaves<\/strong> &mdash; Managing Director of Rolls-Royce<\/div><\/div><\/div>\n<p>And the designer of those winning seaplanes was Reginald Mitchell, who took everything he had learned about speed, streamlining and cooling and applied it to a land-based fighter with elliptical wings. It is too simple to say the Schneider races &ldquo;won the Battle of Britain&rdquo; &mdash; the Spitfire and the Merlin both matured enormously in the years that followed. But without the crucible of the Schneider Trophy, neither would have started from such a commanding lead.<\/p><p>The races ended in 1931, their trophy retired to a display case. Their real legacy took to the air five years later, painted in RAF camouflage, and is still flying at airshows today. Sometimes the most important machines are the ones that teach us how to build the next one.<\/p>\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/nC6Yt7u5ViA\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\n<p style=\"font-size:13px;color:#777;font-style:italic;text-align:center;margin-top:-8px\">The Schneider Trophy air races, 1913\u20131931.<\/p>\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/bu44ztbmI-s\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\n<p style=\"font-size:13px;color:#777;font-style:italic;text-align:center;margin-top:-8px\">Period newsreel of the 1931 British triumph.<\/p><p style=\"font-style:italic;font-size:14px;color:#555\">Sources: Science Museum Group; BAE Systems heritage; Rolls-Royce heritage; The History Press.<\/p>\n<div style=\"background:#f0f4ff;border-left:4px solid #5C91FF;padding:16px 20px;margin:32px 0 8px;border-radius:0 8px 8px 0\"><p style=\"margin:0 0 8px;font-weight:600;color:#333\">Post correlati<\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/the-peoples-fighter-heinkels-he-162-volksjager-was-built-in-72-days-to-be-flown-by-children\/\">The People's Fighter: Heinkel's He 162 Volksj\u00e4ger Was Built in 72 Days to Be Flown by Children<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/fairey-delta-2-world-speed-record-1132-mph-peter-twiss\/\">The British Jet That Flew Faster Than the Sun<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/jetflights\/saunders-roe-princess-flying-boat-too-late\/\">Britain's Giant Flying Boat, Born Too Late<\/a><\/p><\/div>","protected":false},"excerpt":{"rendered":"<p>Before the Spitfire, before the Battle of Britain, there was a series of air races over water &mdash; gaudy, dangerous, and watched by hundreds of thousands.
