A Surprisingly Simple Secret to Supersonic Flight

TL;DR

Engineers overcame aerodynamic challenges to achieve supersonic flight, leading to innovations like swept wings in aircraft design.

Transcript

{♫Intro♫} When the Wright Brothers made their first flight in 1903, people had been trying to fly for centuries. So even though their plane didn’t go much faster than 10 kilometers per hour -- basically, running speed -- it was a major achievement. What’s maybe equally amazing, though, is that it didn’t take another few centuries for us to achieve ... Read More
