At any given time, there are typically around 9,000 to 14,000 planes in the air globally. This number can fluctuate based on the time of day, with peak air traffic often occurring during daylight hours in major regions. On average, during busy periods, there can be as many as 20,000 flights in the air simultaneously. However, these figures can vary due to factors like weather conditions and air traffic regulations.
About 9000 planes fly at the same moment
only 2000 planes take off
Given a line, there are an infinite number of different planes that it lies in.
Only one
we think they are 119 planes in the hold wide world
only 1
Many countries in the world have fighter planes. The very first ones came from Britain, Germany and France around 1915.
two
If 2 points determine a line, then a line contains infinitely many planes.
about 730 planes
how many planes id germany have at start of World War 1
Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
