Why Don't Commercial Planes Fly Faster?

The video discusses the general trend of technological advancements, highlighting how automobiles, ships, and trains have become faster over time. However, commercial airplanes have not followed this trend due to fuel efficiency concerns. Increasing speed leads to higher fuel consumption and costs, which passengers are unwilling to pay. Modern jet engines have improved efficiency, but commercial air travel speeds remain similar to those of decades ago. Supersonic planes like the Concorde faced economic and environmental challenges. Future advancements may lead to faster, quieter flights.
