Two things that helped spark the revolution were the salons and the location of Mexico. The revolution went on for 11 years, with much of it being fought by the peasants and low class citizens. Also, because of this divide the revolution had two different leaders when it first began. Because the country remained divided between upper and lower class, the Mexican forces were able to be easily defeated, thus making the revolution long and drawn out. An effect of this was that the rebel army had many different commanders, thus making it hard for any one of them to lead the revolution for long, with Morelos only serving for four years before his execution in 1815. This frequent change in command made it difficult to bridge the class divide and unite the country.

As proved by the transatlantic flights of Lindbergh and Earhart, postwar airplanes were engineered to fly greater distance.
A transatlantic flight is the one of an aircraft accross the Atlantic Ocean from Africa, The Middle Easte or Europe to North America, Central America and South America or vice versa.
Charles Lindbergh crossed the Atlantic Ocean and landed safety less than 34 years later in Paris. Thus, he became the first pilot to solo a nonstop transatlantic flight, and as a result he changed public opinion with regard the value of air travel and laid the foundation for the future development of aviation.
Amelia Mary Earhart was the first female aviator to fly solo across the Atlantic Ocean. She became a pioneer.
