You take the total population of the world and deduct how many of them are on the surface of the earth at any given time.

On average, there are about 9,700 planes in the sky at any given time. This number can vary depending on factors such as time of day, air traffic, and geographic location. Flight tracking websites like Flightradar24 can provide real-time information on the number of planes in the air.
500 years ago, people did not have the technology to travel in the air like we do today. However, the concept of hot air balloons was being developed during this time, eventually leading to the first successful manned hot air balloon flight in 1783.
The annual average number of airplanes in the air can vary greatly depending on the time of day, day of the week, and season. However, on average, there are estimated to be around 9,700 planes airborne at any given time globally.
According to the World Health Organization, around 7 million people die every year as a result of air pollution. This equates to approximately 19,178 deaths per day worldwide.

Because it is made in a certain way so they stay airborn but at the same time can fit in as many people as they can to reduce the levels of carbon dioxide given out. They are made to have a round nose and a slim body so they go faster and wind and wings so that they can glide through the air :)
