Orville and Wilbur Wright patented a wing-twisting technique as a method for steering an airplane, which eventually resulted in a patent battle as others had fitted their planes with similar mechanisms. The dispute culminated in an October 1914 settlement in which the British government paid £15,000 to the British Wright Company.
