The flight attendant keeps telling you this. Here's why. 😳✈️ Put your tray table up. 😳 It feels like a pointless rule. It isn't. A deployed tray table can trap you in your seat, restrict your brace position, and slow your evacuation when every second matters. During a sudden impact, it can also create additional injury risks for you and increase forces transmitted through the seat structure. With the tray table up, you can brace instantly, exit more quickly, and keep the aisle clear during an emergency. Every rule on that plane exists because something happened before. Science hiding in plain sight. ✈️🔬____________________________________ 🚀 Follow FlyLab for more aviation science every weekday. ____________________________________ #FlyLab #aviation #traytable #aviationsafety #scienceshorts - @flylabyt
