A water landing refers to an aircraft's emergency landing on a body of water, such as an ocean or lake. This situation typically occurs when an aircraft experiences mechanical failure, fuel shortages, or other emergencies that prevent it from reaching an airport. Pilots are trained to handle such scenarios, and specific procedures are followed to ensure the safety of passengers and crew. In some cases, water landings can be planned, such as during test flights or in specific training exercises. Successful water landings depend on various factors, including the aircraft type, weather conditions, and the pilot's skill. Notable incidents, like the US Airways Flight 1549 ditching in the Hudson River, highlight the importance of preparation and training for such emergencies.
