Severe turbulence on an Air India flight injured 17 people after a sudden loss of altitude sent passengers into the aircraft’s ceiling and aisle. The incident prompted an aviation investigation.

Thirteen passengers and four crew members were hospitalized following the turbulence. The force of the encounter reportedly left people inside the cabin injured as the aircraft moved abruptly.

The event has renewed attention on the dangers of severe in-flight turbulence, particularly when passengers or crew are not secured in their seats. Investigators are examining the circumstances surrounding the Air India flight and the sudden disruption during its journey.
