AEROPLANE INTRODUCTION

Aeroplanes are vehicles which are able to fly by being supported by the air, or in general, the atmosphere of a planet. An aeroplane counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines

Although rockets and missiles also travel through the atmosphere, most are not considered aeroplane because they use rocket thrust instead of aerodynamics as the primary means of lift. However, rocket planes and cruise missiles are considered aeroplane because they rely on lift from the air. Another type of aeroplane is the spaceplane which is an aeroplane designed to fly up to extreme altitudes into space and land as a conventional aeroplane.
