If you’ve ever been on a plane, you might have noticed a small black triangle above some windows. At first glance, it seems like just another random marking. But it turns out, these tiny triangles have a surprising purpose — and a flight attendant has finally spilled the beans.
Most of us spend flights either gazing out the window, hoping for a snack, or trying to get comfortable. We don’t usually pay much attention to every little sign or symbol in the cabin. But these black triangles are more than just decoration. They actually mark something pretty important.
A flight attendant who goes by @hennylim on TikTok decided to clear up the mystery once and for all. In her video, she explained that the triangles actually serve two key purposes.

First off, they mark the best seats for viewing the plane’s wings. If you’re someone who loves snapping photos or taking videos mid-flight, choosing a seat near one of these triangles is a pro tip. You’ll have the perfect angle to capture those stunning shots of the wings slicing through the clouds.
But it’s not just about aesthetics. These triangles also help flight crews find the best vantage points to inspect the wings — especially the slats and flaps — during safety checks. It’s a simple yet clever system that makes their job a little easier.
People in the comments of Lim’s video also noted that these spots are often considered “break-in points” on an aircraft. In case of an emergency, rescue teams would use these areas to access the cabin. So, in a way, they serve as a subtle hint at the safest spots on the plane.

But that’s not the only interesting secret Lim revealed. Have you ever noticed cabin crew members sitting on their hands during takeoff? Turns out, it’s not just for comfort. It’s actually a “bracing position” that reduces the risk of injury during an emergency.
The posture involves fastening the seatbelt securely, sitting upright, and placing hands palms up under the thighs with thumbs tucked. Feet should be flat on the floor. Lim demonstrated this position alongside a coworker, explaining that it helps minimize injuries if something unexpected happens.
While they’re sitting like this, crew members are also doing “silent reviews” in their minds. They’re mentally running through emergency procedures, checking the location of safety equipment, and staying alert to anything unusual inside or outside the plane.
Although it might seem nerve-wracking to think about, it’s comforting to know that the crew is always prepared for anything. One commenter admitted that it’s a bit unsettling to think about the crew being ready for a crash on every flight. But Lim reassured everyone that while the odds of an accident are incredibly low, staying prepared is just part of the job.
Next time you fly, take a peek for those little black triangles and remember — they’re more than just a quirky detail. They mark the best view in the sky and serve as an important safety feature. Plus, now you know where to sit for those envy-worthy wing shots!
