Jets fly through the stratosphere, which is the second layer of the Earth's atmosphere. The stratosphere contains the ozone layer, which helps to absorb and block harmful ultraviolet radiation from the sun.

To avoid turbulence, most commercial jets fly in the upper layer of the troposphere, which varies in height depending on latitude, typically 40,000 feet (5 km). This is on the border of the tropopause, just above the troposphere, and the lower layer of the stratosphere in some cases.

they have wings and engines
Because space ships are too high up in the atmosphere and the other option, balloons, are pretty boring.
Airplanes fly inside the atmosphere which is made up of 4 levels. The atmosphere starts at sea or ground level and when it ends you are in outer space (no longer on earth). Majority of all planes fly in the first level of the atmosphere called the Troposphere which ends around 50K feet. Military jets and spy planes usually fly in the second atmosphere called the stratosphere.
The fly and then they shoot (:

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.
