Yesterday, the 7th December was International Civil Aviation Day, a global celebration organised by the International Civil Aviation Organisation (ICAO). The purpose of the global celebration is to generate and reinforce worldwide awareness of the importance of international civil aviation in the social and economic development of States, and of the role of ICAO in promoting the safety, efficiency and regularity of international air transport.
Perhaps this is a good time to read about flying and how it has changed our world. You could read about some famous aviators such as the Wright brothers or Amelia Earhart. Both of these are subjects in DK readers - First Flight: The Wright Brothers by Caryn Jenner and Amelia Earhart by Tanya Lee Stone. You could look at how Qantas began, the Flying Doctor Service or just do a picture study of how planes have changed. Books such as DK Big Book of Airplanes by Caroline Bingham or the new Flight: 100 Years of Aviation by Reg Grant are good for this. The latter is too hard to read for younger children but the pictures will keep them absorbed.
