Aero (1) Commander 520
The Commander 520 was Ted Smith's original Aero Commander design, a twin-engine, high-wing executive aircraft he created after leaving Douglas, where he had worked on the A-20 and A-26 attack bombers. It first flew as a prototype in 1948 and reached production at the Bethany, Oklahoma factory in 1951, powered by two 260-horsepower geared engines. Its raised cockpit, set well above and ahead of the wing, gave excellent visibility and a distinctive profile. A military U-4B version of the 520 served as President Eisenhower's personal transport from 1956, the smallest aircraft ever to carry the informal 'Air Force One' title.
