"The course of the flight up and down was exceedingly erratic, partly due to the irregularity of the air, and partly to lack of experience in handling this machine. The control of the front rudder was difficult on account of its being balanced too near the center"

This quote is from Orville Wright, one of the developers of the very first successful airplane. He is describing the experience of flying the first aircraft. The flight was unpredictable, suggesting it was not smooth or consistent. This was due to two aspects: the air was not consistent, and the pilots lacked experience in flying the machine. The control of the front rudder was hard since it was balanced too near to the center. This made it tough to control the airplane, as the pilots needed to make more adjustments to keep the plane in the air. The unpredictable flight and absence of experience in handling the maker made it difficult for the pilots to keep the aircraft in the air. Regardless of the problems, the Wright bros were able to successfully fly the very first aircraft, paving the way for the development of modern air travel.
