Patrick Alexander was very interested in the development of heavier-than-air flying machines. Early in the 1890s, he travelled to Germany to meet Otto Lilienthal who was experimenting with gliders, and he continued to study ideas from a wide variety of sources. In 1896, Hiram Stevens Maxim came close to achieving flight when his huge steam-powered machine briefly lifted from the rails that also restrained it. Patrick was in contact with Octave Chanute and others experimenting with flight. In the USA, sometime before 1903, Patrick visited Samuel Pierpont Langley whose successful models had attracted much attention. At Christmas 1902 he visited the Wright brothers at Kitty Hawk.
