Air India flight AI2379 suffered a sudden altitude drop during severe turbulence on Tuesday, Aug. 4, injuring multiple passengers [1, 2].

The incident highlights the continuing risks of severe clear-air turbulence and the critical importance of passenger restraint systems during flight.

The aircraft was traveling from Phuket, Thailand, to Delhi, India, when it encountered the atmospheric disturbance [1, 3]. According to reports, the plane suddenly dropped approximately 300 feet [2, 4].

Reports on the number of casualties vary across sources. Metro said that at least 17 passengers were injured [2]. Other reports listed the number of injured individuals as 12 [3] or at least 10 [1].

Indian authorities have opened an investigation into the cause of the altitude loss and the subsequent injuries [5, 2]. The investigation will likely focus on weather data and the flight's operational logs to determine why the aircraft experienced such a significant drop.

Severe turbulence can occur without warning, even in clear skies, making it difficult for pilots to avoid. This event adds to a series of global reports regarding increased turbulence incidents in recent years, a trend often linked by meteorologists to changing atmospheric conditions.

The discrepancy in injury counts suggests early reporting volatility, but the confirmed 300-foot drop indicates a significant meteorological event. This incident underscores the operational challenges airlines face with unpredictable turbulence, which can lead to passenger injuries even when aircraft remain structurally sound.
