If you’ve ever watched the flight attendants and flight attendants carefully during takeoff, you may have noticed a particular gesture: they sit up straight, with their backs firmly supported by the seat, their legs together and their hands under their thighs.

At first glance it seems like a rigid, almost uncomfortable posture, but behind this movement there is a key reason related to safety. A flight attendant revealed why they do this and what purpose this small but significant detail fulfills.

Why do they sit on their hands during takeoff?

The most critical moments during a commercial flight are takeoff and landing. For this reason, the crew adopts a position called “bracing position”, designed to protect the body and be ready for any eventuality.

Here’s why they place their hands under their thighs:

1. Avoid involuntary reflexes

By placing the hands under the body, personnel avoid the urge to use their arms in the event of an impact. This helps prevent wrist, arm, or shoulder injuries caused by instinctive, uncoordinated movements.

2. Keep the body firm and aligned

Sitting with your back straight and your legs together allows the body to absorb the impact more safely. The hands under the thighs ensure that there are no sudden movements of the upper body, reducing the risk of dangerous displacements.

3. Facilitate the assessment of the environment

With the body stationary, the crew can concentrate fully on observing the cockpit, listening for abnormal noises and acting quickly if something happens. This posture gives them greater control and attention.

4. Minimize damage in case of emergency

In the event of a quick evacuation, having their hands protected under their thighs reduces the risk of fractures or burns, allowing them to use them immediately when getting up or opening doors.

Tips and curiosities you may not have known

• The posture is trained in detail. It is not improvised. All crew members go through specific training to adopt it correctly.
• It’s not just when you take off. They also use it during landing or severe turbulence.
• Don’t cross your feet. If you’re in a seat, try to maintain a firm posture. Crossed feet can cause injury if there is harsh braking.
• Watch and learn. Knowing why they do this can also help you adopt a better posture as a passenger.

Behind every gesture of the flight crew there is a safety protocol thought out in detail. Sitting on your hands during takeoff is not a mania or a fluke, but a well-thought-out strategy to protect yourself and be ready to act in seconds. The next time you take a plane, pay attention: that small gesture can make a big difference.
