Using Lilienthal's glider research, the Wright brothers achieved controlled flight. The French reacted with renewed effort and Bleriot crossed the English Channel. Each airplane had its own personality and a pilot flew by his wits, instinct and luck.

Aviators separated into two groups: the airplane designer/builders and those who tried to master the art of flying. While French pilot Pegoud thrilled crowds by performing aerial loops, new airplanes pushed the bounds of speed and distance.

WW1 gave the airplane a job, soon the battlefields were full of unarmed aircraft, peering down at the trenches, then carrying news of an impending attack. With a machine gun mounted on the cowling of a Morane-Saulnier Bullet, the fighter plane was born.

After the war, seasoned pilots who had once dueled with an enemy over the trenches, now performed aerobatics for spectators. Aviators as barnstormers quickly became an endearing folk hero; and also businessman carrying mail and passengers.

Airmail pioneers demonstrated that airplanes had a bright commercial future. The variety of aircraft was dazzling -- anything with wings was put to use. But conditions were harsh and pilots had to be hardy and brave to risk flying the mail.

In the 1920s when just about anyone could afford a car, interest grew in a safe, inexpensive airplane that anyone could fly. Convenience went a step further in roadable aircraft -- vehicles that could travel the highways, then convert to an airplane.
