Aviation before World War I was a laboratory, open primarily for the self-motivated engineer, rich hobbiest or gifted amateur enthusiast. Largely absent were the military, industrial or commercial interests to overcome technological problems with the brute force of large bankrolls.

Despite the obstacles, barriers fell and new goals suddenly appeared within the grasp of aviators. Agile aircraft appeared that could loop, roll and climb to higher altitudes.
