First Flights With Neil Armstrong

The ultimate test of aircraft and pilot was to fly around the world. Competition and showmanship were always a part, but it was the mental and physical endurance of the men and women who climbed into the cockpit that made success possible.

During the 1960's, the general population embraced air travel. Larger airplanes were needed, with lower noise levels. The pilot's role changed to meet the demands of the developing airlines. Jumbo and narrow body jets were developed.

Ultralight airplanes evolved from hang gliding enthusiasts' attempts to glide further by adding small engines and propellers. Now reliable, tested ultralights are flown by multitudes of recreational pilots.

The turboprop is a mix of two successful technologies, the jet turbine and the propeller. Highly reliable, the turboprop has been the workhorse of the skies for decades, and remains the mainstay of commercial short-haul aviation.

From Cierva's autogyro, to the BK-117, the heart of the helicopter has been the rotorhead. Early helicopters were complex, dangerous machines, prone to failure. For the men and women who took the controls, concentration and daring were essential.

By the 1930s, flying boats and seaplanes were the craft of the future. Flying boats -- massive, airborne ocean liners -- opened up global routes for passengers, while floatplanes were the fastest, most innovative flying machines in existence.

Conventional airplanes need large runways, a limitation that concerned defense planners. As turbine engines became lighter, a new breed of aircraft became possible -- one that could take off and land vertically, yet fly with the speed of jets.

When the small tail wings which enable an airplane to go up or down are moved to the front, they are called canards. It was an almost forgotten technology as old as manned flight, but canards are making a bold reappearance on the modern aviation scene,

Searching for flight efficiency, some designers thought the ideal shape should be just a wing. Though development of flying wings has often proved illusive, Northrop's designs proved feasibility. The B-2 Stealth Bomber shows the concept holds promise.

In the early days of flying, a weighted silk stocking tied to a strut might help the pilot gauge his airspeed. Wartime forced pilots to learn the skill of blind flying. Today, orbiting satellites and autopilots enable an aircraft to fly itself.

Two years after the first manned flight, the Wrights mastered control sufficiently to fly the first circle. By WWII, the first hydraulically boosted controls were invented. Digital flight control, fly-by-wire technology, has become state of the art.

The Wright brothers realized that a propeller was a rotating wing.In the 1930s, variable pitch and NACA research revolutionized propeller design. Today, fast turboprops with advanced propellers can be more efficient than the best jetliners.
