Most planes fly in one layer of the atmosphere called the troposphere. High flying aircraft can fly into the stratosphere
Aircraft fly in the troposphere because the stratosphere is where the clouds are. Here all the weather fronts take place. So, to avoid major turbulence, aircraft fly here.
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.
