#8: Air France Flight 447 (2009)
On an overnight flight from Rio de Janeiro to Paris, the Airbus A330 encountered stormy weather over the Atlantic. Ice crystals blocked sensors, causing faulty speed readings. Confused by conflicting warnings, the pilots lost control, and the plane plunged into the ocean, killing all 228 people aboard.

The wreckage took nearly two years to locate on the ocean floor, sparking intense mystery and debate. The investigation revealed shortcomings in pilot training for high-altitude stalls and reliance on automation. The tragedy pushed airlines to retrain crews for manual flying skills and highlighted how modern technology can sometimes fail in critical moments.
