Final answer:
Designing and building a rocket is more difficult than designing and building a plane.
Step-by-step explanation:
In terms of difficulty in design and construction, it would be more challenging to design and build a rocket compared to a plane. Rockets are more efficient in outer space than in Earth's atmosphere because the air in the Earth's atmosphere does not provide thrust but does create more air friction than in outer space.
The article mentions that rockets are more efficient in Earth's atmosphere due to the air providing thrust and less air friction than in outer space. However, in terms of overall design and construction complexity, rockets face more challenges. For instance, rockets need to achieve a greater final velocity to orbit the Earth, requiring longer acceleration time. Additionally, rockets work better in a vacuum, where they can expel exhaust gases more easily.
In summary, although rockets may have some advantages in Earth's atmosphere, their complexity and design challenges make them more difficult to build compared to planes.
