Air India Express Flight 812 was a scheduled passenger flight from Dubai, UAE, to Mangalore, India, operated by a Boeing 737-800. On May 22, the flight was attempting to land at Mangalore International Airport, which is known for its challenging geography and has a tabletop runway that requires precise approaches from pilots. As the aircraft approached the runway, it overshot and failed to stop in time due to the wet runway conditions and possibly other factors such as pilot error and mechanical issues.

After overrunning the runway, the aircraft plunged over a cliff, ultimately breaking apart upon impact. Although there were 166 people on board—including passengers and crew—only 8 survived the disaster, making it one of the deadliest aviation accidents involving a Boeing 737. The crash raised significant concerns over the safety protocols at airports with similar terrain and led to in-depth investigations by both Indian authorities and aviation experts.

As a consequence of the accident, a comprehensive review of runway safety measures and pilot training procedures was initiated. The incident underscored the importance of developing better safety regulations in challenging aviation environments, thereby influencing future infrastructure and training protocols at international airports, especially in topographically challenging regions.
