What came after?
After the Wright Brothers had flown the first successful plane with an engine, the so called 'practical plane' became very popular. The designs improved and then became useful all over the world. Cargo, travel, war, and sightseeing are just some uses that the plane can be used for, allowing for a massive multi-billion dollar industry to arise around the plane. The aircraft has become a necessity for modern life, and are constantly being improved and re-designed to be better and more efficient. They are used now more than ever and have been specialized for each different use.
