Aeroplanes having wings fly at low altitudes while jet planes fly at high altitudes . Way ?

Explanation

The wings of an aeroplane push the air backwards . The aeroplane noves forward due to reaction of the pushed air At lower altitudes, air is dense . Therefore, The plane receives sufficient reactional push to move forward . In a jet plane , external air is sucked into the plane and compressed Therefore, jet planes fly at high altitudes where air density is small .
