The technology on airplanes is not old, the concept of some things might be and it is simply because they work and they are reliable.
No and never have
Yes they did. In the 80's airplanes had smaller engines and less aerodynamic. Modern technology allows for a plane to increase its speed.
Airplanes.
Modern aircraft are heated and cooled inside by 'bypass airflow' from the engines.
Modern airplanes are built in the current year
The Wright Brothers airplanes were made of wood and cloth. Modern airplanes have metal fuselages (which means that its a closed object, unlike older planes). Modern airplanes are pressurized, which means you can breath at high altitudes. Newer airplanes can carry much more passengers and has much more range. Most new airplanes have either turboprop, turbofan, or turbojet engines, which are much more fuel efficient, less noisy, and more reliable, whereas older airplanes used piston airplanes. They also have more sophisticated technology, such as fly by wire, turbulence avoidance, etc.
We see modern technology everywhere now.Some of the examples of modern technology in terms of transportation are cars, airplanes, etc.Examples of modern technology in terms of health are x-rays, mri, different types of scans, etc.In similar ways, we can pretty much pick anything in life that is affected by modern technology.
Yes, steam engines are still used in some modern industries and technologies, particularly in power generation and certain types of transportation.
The modern technology available in the Land Rover Defender would include more modernized engines and transmissions, interiors. It has also added the turbo-diesel engine.

Airplanes were needed in the 1800s because businesses needed to move their products faster and consumers needed to get to places quicker. The demand for airplanes led to the invention of airplanes.
There are many differences between modern airplanes and older airplanes. The two most significant improvements have are newer more fuel efficient engine as well as structural redesigns such as the wings.
