Montgomery Hill

Three-quarters of a mile northeast is Montgomery Hill, site of the 55 successful flights of John Joseph Montgomery's 'aeroplane' that demonstrated aerodynamic developments still indispensable to modern aircraft. Montgomery combined his engineering skill with the basic principles of aerodynamics that he discovered to produce a heavier-than-air flying machine which had complete control: cambered wing, rear stabilizer, flexible wingtips, and wing-warping aileron.
