Planes have multiple uses. They are used for military use, shipping and receiving, travel, sightseeing, fire control, and more. Planes have revolutionized the way we travel and fight in wars today. They have multiple designs for different uses and needs. The military planes that transport jeeps, hummers, and other big vehicles don't have rows of seats, but fold up seats along the inside walls of the plane. They do this so that they can fit those vehicles on the inside of the aircraft. They created certain aircrafts for certain uses, such as passenger planes for travel that are just meant for passengers and their baggage. On the other hand, cargo planes such as FedEx, or UPS just have a pilot, maybe some seats for the crew members, and the rest is all cargo area that might consist of shelves and other types of storage. Each plane is designed for an individual purpose.
