Aircraft

Aircraft are a type of vehicle built and used in unus solum that is characterized by flight. In order to fly an aircraft needs to create an upwards force or lift in order to counteract gravity. Aircraft types are categorized by how they generate this lift force.

In the world there are two types of aircraft primarily in use: Lift-cage aircraft (also known as wingless aircraft or airships) that generate lift through a lift cage, either spin or rigid, and Fixed-Wing aircraft which utilize airfoils (also known as airplanes).

Secondary types include hybrid aircraft that utilize rigid cages in conjunction with airfoils, hot air or hellium baloons, among others.
