The invention of the plane impacted warfare greatly, ushering in new strategies and giving aviation a key role in wars. At first no weapons were fitted on the planes themselves. The pilots carried handheld weapons, but soon the planes developed to have machine guns built onto them. Planes were used to drop bombs and attack other planes. Bombers also brought a negative effect as more innocent citizens were affected by combat.

In 1939, the physicist, Hans von Ohain, invented the first jet plane. This invention kickstarted the Jet Age. Jet planes are capable of much higher speeds and height. The first commercial jet airliner was the British De Havilland Comet. This led to much faster transportation. The XS-1 research plane first broke the sound barrier in 1947 when it was carried in the air under a B-29 and dropped, with the plane speeding at the speed of sound. This showed that planes had the potential to go very fast.

Planes also soon evolved to carry cargo around the world because of how fast they could easily fly across the world. This resulted in 44.5 billion pounds of freight getting carried by planes every year.
The plane also revolutionized worldwide communication, connecting the world through quick and efficient mail delivery. Flight is common now, with the FAA approving 45,000 flights every day. Aviation creates jobs, around 10 million. Airplanes carry over 10.8 million people every day and aviation has $488 billion annual earnings.

In conclusion, the invention and innovation of aviation was a significant turning point in the history of the world by speeding up transportation, communication and completely changed how wars are fought.
"I confess that in 1901, I said to my brother Orville that man would not fly for 50 years."
