"Missing Aircraft" refers to an aircraft that has lost communication or failed to arrive at its intended destination without any known reason. This situation can occur due to various factors, including mechanical failure, adverse weather conditions, or human error. When an aircraft goes missing, search and rescue operations are typically initiated to locate the aircraft and its occupants. The disappearance of an aircraft can lead to significant investigations by aviation authorities, such as the Federal Aviation Administration (FAA) or the National Transportation Safety Board (NTSB). These investigations aim to determine the cause of the disappearance and improve safety measures to prevent future incidents.
