Which layer of the atmosphere is the highest an airplane can fly?

Answer 1

Airplanes fly in the Stratosphere, which is the second major layer of the Earth's atmosphere. It is below the mesosphere and above the troposphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down. The winds in the stratosphere run parallel to the Earth in fast moving air streams. 

Answer 2

Planes typically fly in the lowest layer of the atmospehere which is know as the the troposphere. (pronouced: tro - po - sfeer)

Answer 3

Most aircraft fly in the lowest layer, the troposphere.

Answer 4

Stratosphere
Troposphere and lower strarosphere. Most commercial jets fly in the lower stratosphere.

Answer 5

Airplanes fly in stratosphere. It is a layer of atmosphere.

Answer 6

Commercial jets fly around the midpoint of the troposphere, the lowest layer of the atmosphere.

Answer 7

stratosphere

Answer 8

Depends. Spaceship one developed by Bert Rutan flew out into the legal definition of space, Then all the way to the ground. General commercial aviation type aircraft big jets fly the stratosphere.

Answer 9

Airplanes don’t fly in the earth. They fly in earths atmosphere. All the way upto space.
