In-flight turbulence, unpredictable air movements, can pose significant hazards to passengers and crew. Despite its rarity, turbulence has caused injuries, including a recent fatality on a Singapore Airlines flight. Experts advise wearing seat belts and staying vigilant during flights, as turbulence can occur without warning. Clear-air turbulence, the most dangerous type, is challenging to predict and can lead to severe injuries. While planes are designed to withstand turbulence, it can cause cabin damage. Climate change may contribute to increased turbulence, as jet streams and wind shear could be affected.
