Welcome to the "Lars From Mars - Learning Videos for Toddlers". In this episode you will learn about different types of plane. Planes can arise as subspaces of some higher-dimensional space, as with one of a room's walls, infinitely extended, or they may enjoy an independent existence in their own right, as in the setting of Euclidean geometry. There are a number of ways to identify aircraft by type. The primary distinction is between those that are lighter than air and those that are heavier than air.
Airplane, also called aeroplane or plane, any of a class of fixed-wing aircraft that is heavier than air, propelled by a screw propeller or a high-velocity jet, and supported by the dynamic reaction of the air against its wings. For an account of the development of the airplane and the advent of civil aviation see history of flight. Along with Boeing company, aircraft manufactured by Boeing are also very famous.
