First Airplane
In 1903, Orville and Wilbur Wright created the first motor-powered airplane, and it flew on December 17, 1903. The flight lasted for only twelve seconds, and it flew a total distance of one hundred twenty feet over Kitty Hawk, North Carolina.When Orville and Wilbur Wright created the first successful airplane, it was a good foundation for airplane engineers to build off of and improve.
First Metal Airplane
In 1917, an all-metal airplane was created, the Junkers J4. Hugo Junker, the designer of the Junkers J4, built this plane out of duralumin, lightweight aluminum. Aeronautical engineers discovered that there were several advantages of using metal over the previous wood ones. Metal was more durable, it protected the aircraft from fire, did not corrode, did not absorb sun or moisture, and it provided the aircraft with a sturdy structure.
First Radar
in 1935, Robert Watson-Watt, former meteorologist, patented the first radar. The term radar was short for “radio detection and ranging.” The system that he invented was called “Chain Home”. This system was frequently used in World War II to track incoming aircrafts and provide information about nearby bombers. It was also used for weather and location purposes. Radars were most useful during wars or battles, because the pilots could detect bombers miles away from their plane. the older ones did not have a radar system, so pilots were not aware of their surroundings.
First Jet Engines
In 1937, Frank Whittle and Hans von Ohain designed the first jet engine, which was made up of a fan, compressor, combustor, turbine, and nozzle. On August 27, the Heinkel HE 178 was the first aircraft to successfully fly with von Ohain’s HE S-3 jet engine. This innovation helped airplanes fly faster and more efficiently, because the engines were more powerful. The jet engines were also compact in size and simple to design.
Commercial Airplanes
In 1949, the first jet-powered commercial aircraft took flight on July 27, 1949. In 1969, twenty years later, the Boeing 747 was the first commercial airplane that had a wide-body and turbofan-powered engines. This aircraft was one of the most successful ones produced. It had four engines, two decks, and it flew at high speeds. By creating the first commercial aircraft, this was the first step toward passenger transportation. This was something airplane engineers never thought about until now.
First Airplanes Difficult
To Detect By Radar
In the 1990s, Northrop Grumman developed the B-2 bomber, which was made out of composite materials rather than metal. This could not be detected using conventional radar. Composite materials were the second most important material engineers used when building airplanes, and the most common composite material was fiberglass. Compared to older airplanes constructed out of wood and metal, composite materials were lightweight, strong, more aerodynamic, and simple to assemble. The lighter the airplane, the less fuel it burned; this was very important to Aeronautical engineers. Around this time period, another plane was designed that was also difficult to detect by radar, the F-117 stealth fighter. These types of planes were mainly used for military purposes, because other planes could not detect their bomber planes on the radar. Metal-Skinned Aircraft.
Airbus A380
It's the largest passenger jet ever built ,so huge that airports have to be redesigned to accommodate it. It can pack in more passengers and cargo than any other commercial airliner, yet its designers claim it will actually increase efficiency, use less fuel and generate less noise.
The 555 seat, double deck Airbus A380 is the most ambitious civil aircraft program yet
It is able to fly a distance of over 10,000 miles, the plane's usefulness will not be limited to long-haul flights.
Project Completes Flight Research for Cleaner, Quieter Aircraft.
EDWARDS, Calif. - NASA's remotely piloted X-48C hybrid-wing-body subscale aircraft, which demonstrates technology concepts for cleaner and quieter commercial air travel, completed an eight-month flight research campaign on April 9.
The best advantage that the airplane brought is it´s speed
Airplanes have provided many benefits to travelers, transporters, and military alike. With the use of air travel we would not be where we are today. People enjoy the convenience of air travel for vacations, visiting loved ones, and to quickly travel from one city to another for work purposes. We are able to transport goods from one area to another with in shorter period of time than land travel.
It opens up our minds and increases our understanding about the world.

One disadvantage of the airplane is that in many occasions the tickets are very expensive and not everybody has the money to buy one. That is why, nowdays there are some people who have never traveled by plane.
Another disadvantage that we can see is that we can feel uncomfortable in the seats when the flight is too long, we connot go out and take some fresh air like we do on a boat, it is also forbidden the use of cellphone and our personal space is not enough.
I want to study aviation and become an excellent pilot, this is why I think that the airplane was an incredible invention because it is a conveyance that allows us to be in a different world in a couple of hours, also we can learn about new cultures, their habits, way of living and typical food, to talk and share with new people and going to faraway places which would be impossible to reach by water or by land, also visiting our loved ones that live in other countries.
