An airplane crash occurs when an aircraft unexpectedly collides with the ground or water, often resulting in damage and potential loss of life. Various factors can contribute to such incidents, including mechanical failure, human error, or adverse weather conditions. Investigations are typically conducted by aviation authorities to determine the cause and improve safety measures. The aftermath of an airplane crash can involve search and rescue operations, recovery of wreckage, and support for victims' families. Organizations like the National Transportation Safety Board (NTSB) in the United States play a crucial role in analyzing crashes to enhance aviation safety and prevent future accidents.
