A Brief History of Airplanes and Aviation SafetyThe history of airplanes and helicopters in aviation is still a relatively short chapter. However, the amount of progress between the Wright brothers first flight and current aviation is nothing short of amazing. The leap in aviation technology can be attributed to the advancement in computer technology and the demand for safer and more efficient airplane designs for war, business, and air travel. 
No history of aviation is complete without mention of the Wright brothers. While there were numerous prior aircraft designs and flight attempts, the Wright brother’s airplane design would set the standard for the future. Their 12-second flight in 1903 was the first controlled, engine-powered flight with a heavier-than-air aircraft (as opposed to balloons and blimps). It's when the history of airplanes really began.A New Era
World War One (1914-1918) ushered in a new era of flight.Pilots began to need a system for communicating with their commanders and ground personnel, and the first communications equipment was invented - the radiotelephone. The standard materials of wood and fabric were replaced by aluminum, which was lighter, faster, and safer. As capturing new flight records and performing acrobatics became popular, biplanes were phased out for the development of monoplanes, which were sleeker and more maneuverable. 
By the onset of World War Two (1939-1945) flight instruments had been invented, airplanes were equipped with radar, and the first jet engine was already in production.Following the world wars, the age of jet airliners began, as airline companies like Pan Am and airplane manufacturers like Boeing combined to transport millions of passengers around the world. High cruising altitudes and transoceanic flights were the results of improved aerodynamics, aircraft metal types, and improvements of the engines. History of Airplane Design
The single greatest step in the history of airplane design was the introduction of the jet engine. Turbine powered engines transformed the aviation world, by drastically increasing the speed, rate of climb, maneuverability, and distance travelled. All large transport aircraft are equipped with more than one engine, so if one engine fails there are back-up engines that will provide enough power for a safe landing. Along with jet engines came the need for cabin pressurization. A cabin pressurization system maintains ground level pressures inside the airplane, so the airplane can safely ascend to a high altitude cruising level. High altitude cruising is more efficient and keeps the airplane above turbulent altitudes, making the trip more comfortable for passengers and crew, as well as lessening the stress on the airplane. Current changes in airplane design include the use of technologically advanced communications, radar, global positioning systems (GPS), and autopilot systems. These help pilots navigate busy airways and fly safely around severe weather. The autopilot and various alert systems are not a replacement for hands-on flying, but aid the pilot by providing flight assistance as needed so other flight management tasks can be accomplished.
