Model aircrafts are small-sized representation replicas of existent or theoretical aircraft. Model aircrafts are divided into two categories: flying and non-flying models.
In flying models, we can find details from rudimentary toy gliders made from thin cardboard to battery-powered scale models made from plastic, fiberglass, carbon fiber, and an extensive assortment of different materials. Their sizes vary from small to about the 2/3 the length of a sports bicycle and some are constructed to serve as economically-sized test models for the flight properties of proposed full-scale models. Most airlines around the world request their aircraft to be modeled as a self-promotion effort, this includes Delta, Aerolineas Argentinas, Aeromexico, Polar Air Cargo, Avianca, British Airways, United, Lufthansa, Japan Airlines, American, Korean Airlines, Finnair, China Airlines, And Singapore Airlines.
These publicity efforts by airlines are not limited solely to museums. Airlines also provide small-sized replicas of their aircraft to airports, airlines, and government officials as a courtesy gift for celebrating a milestone. Alejandro García Padilla, former Puerto Rico Governor has models of Lufthansa, JetBlue, Seaborne, and Avianca Airlines planes given to him by those airlines for his efforts in increasing flight from and to Puerto Rico during his tenure.
