Airplanes are pretty amazing machines. Many of us consider them to be the “miracle of engineering”, because without them, it would be almost impossible to travel overseas to other continents and really experience life through travelling. Not only this, but airplanes were one of the most important machines in World War II, which made the aircraft industry receive a huge investment, and be able to create more weapons. Fortunately, the War is long gone, and the planes used during this time only exist now to show us some really incredible skills in the sky. Here is a special selection of 30 awesome pictures of aeroplanes performing shows in the sky.
