This refers to the advancements in aviation technology that have allowed airplanes to travel faster, further, and more fuel-efficiently.
Think of it like upgrading your old bicycle to a new electric bike. The new bike can go faster, cover longer distances, and uses energy more efficiently.
Aerodynamics: The study of how air moves around objects. In terms of planes, better understanding of aerodynamics has led to design improvements that increase efficiency.
Jet Engine: A type of engine that propels an aircraft forward by ejecting a fast-moving jet of fluid (usually hot gases from burning fuel). Jet engines have greatly increased the speed and efficiency of air travel.
Carbon Footprint: The total amount of greenhouse gases produced directly or indirectly by human activities. Increased plane efficiency helps reduce the carbon footprint associated with air travel.
