On this day, 81 years ago, on March 8, 1944 (February 14, 1944 in the lunar calendar), Spitfires exerted their power in the battle against Germany. Spitfires were the main force in thwarting German air strikes on Britain. In March 1944, the aircraft that contained the German Air Force's arsenal and prevented a war against invading Britain have now been equipped with a more powerful engine, which has since driven the German army back to bases in their own country. The single-engine Spitfire, known by the Royal Air Force as the soul of the air, shot down many German fighter jets and bombers, causing the Germans to abandon their plan to first raze Britain and then land it on the mainland. Another new, high-powered, and more rugged Rolls-Royce engine is the same model used in the Blue Jays racing car that broke the record in the Malcolm Campbell race.
