Upside down with the Blue Angels, Be Smart investigates lift

Joe Hanson builds a smoke-filled wind tunnel after a fighter-jet ride raises a deceptively simple question.

  1. 1:04A homemade 3D-printed wind tunnel uses smoke and laser lighting to reveal airflow around wings.
  2. 5:52Hanson sets out the familiar Newton and Bernoulli explanations, arguing neither alone supplies a satisfying account.
  3. 7:43Air passing above and below a wing does not have to reach the trailing edge together.
  4. 10:55Hanson explains lift through turning airflow and the lower pressure on the inside of its curved path.
  5. 14:55Stalls, symmetrical wings and inverted flight illustrate how the explanation applies beyond a conventional curved airfoil.

How can a plane stay aloft when its wings are upside down? Joe Hanson returns from a Blue Angels flight with that question, then builds a 3D-printed wind tunnel to work through it at home. Smoke and laser lighting make the invisible air currents visible.

"The Most Misunderstood Idea in Flight" was Be Smart's only upload this week, reaching more than half a million views. The cockpit footage supplies the physical stakes: Hanson endures sustained high-g turns over Pensacola, with pre-flight training showing the effort required to stay conscious. The video includes an AnyDesk sponsorship.

Back at the experiments, Hanson challenges the familiar story that air traveling over a wing must meet the air passing underneath at the trailing edge. "Equal transit time is a myth," he says. His central explanation arrives later: wings turn the airflow, producing the pressure differences that generate lift. Symmetrical wings, stalls and inverted flight become tests of that explanation rather than exceptions to it.

The comments keep the lesson going. Viewers debate how his account connects Newton's laws with Bernoulli's principle, while others ask why curved airflow has lower pressure on its inside. Several focus specifically on angle of attack and how the airflow diagrams communicate pressure.

Be Smart's daily views are running above their usual level, although its subscriber total stayed unchanged over the week. Among nearby science channels, Miwu Science had a much larger week for views, while minutephysics had a quieter one. Hanson's flight lesson now supplies most of Be Smart's daily viewing; "Your mom's cells are still inside you" and "Why are there no green mammals?" remain its next busiest uploads.

What viewers say

  • I came to this video wanting to understand how wings generate lift, but I left wanting to understand why vortexes have lower pressure on the inside.

  • The hard part for me with these visuals is that lines closer together make my brain think of higher pressure. Which isn't really shown in the air over wing image (at least under the wing), and is especially confusing in the tornado image. Looks higher pressure at the center not lower.

  • Incredible experience! We were happy to have you in Pensacola, Joe!
