Airplanes are high-tech machines with advanced technology. The yellow hooks on airplane wings might not seem like much, but they are important for your safety.
Airplanes are one of the best examples of thoughtful engineering. Most of the things you find on an aircraft have a special purpose behind them, and there will rarely be a feature that has been added just for aesthetics. Whether it’s the headlights, the tiny hole that you find in an airplane window, or the ashtrays in plane bathrooms, the presence of every item in an aircraft has meaning behind it. There’s another small but important item that you’ll find on airplane wings — yellow hooks that look like a frog’s eyes.
While airplane manufacturers try to make sure that the planes are as aerodynamic as possible, they still add these hooks on the wings because of their important use case.
