Aviation has its origins in prehistory when humans first imagined flying like birds. Over centuries, many pioneers attempted to build flying machines but it was not until the 1900s that the Wright brothers achieved the first successful powered flight. Since then, aviation has evolved rapidly with commercial flights beginning after World War 2 and modern aircraft like the Boeing 777 designed entirely using computer technology. Today there are over 4,000 planes in the air every hour, demonstrating how aviation has transformed global transport and become the safest mode of travel.
