Expert Solution & Answer

- Various variabilities are also there in the engine as modern engines are high-bypass engine, with engine there is also change in the usage of raw material and because of this the airframes are comparatively lighter.
- However, modern airways do pretty much the same thing compared to the airliners of 1960s but there is a huge difference in technology, which is not viewed by the people.
