Why do planes fly at 37000 feet?
The biggest reason for this altitude lies with fuel efficiency.
The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed.
Less wind resistance, more power, less effort, so to speak.
Spending less on fuel is also great for airlines, for obvious reasons..
What is kept in an aviary?
An aviary is a large enclosure for confining birds. Unlike birdcages, aviaries allow birds a larger living space where they can fly; hence, aviaries are also sometimes known as flight cages. Aviaries often contain plants and shrubbery to simulate a natural environment.
