Sikorsky's pivot to conventional planes in Russia was nothing short of spectacular. By 1913, he had designed and personally flown the world's first four-engine airplane, the Russky Vityaz (or Grand ), an aircraft so large it was decades ahead of its time. He followed this with the Ilya Muromets , an even larger four-engine plane that was converted into a heavy bomber for the Imperial Russian Air Force during World War I, becoming the world's first long-range strategic bomber. These achievements established him as a premier aircraft designer in Europe.
Sikorsky remained deeply involved in the testing phases of his aircraft throughout his life. He was famously known for wearing his trademark fedora hat while personally test-piloting his early helicopter prototypes, demonstrating absolute confidence in his engineering calculations.
