Loss of Communication and Radar Contact: MH370 vanished from air traffic control radar screens less than an hour after takeoff from Kuala Lumpur International Airport. The sudden loss of communication and radar contact with the aircraft is one of the central mysteries of the case.

Deliberate Action or Human Intervention: Investigators have not ruled out the possibility of deliberate actions or human intervention as a cause of the disappearance. This includes scenarios such as hijacking, sabotage, or actions taken by individuals on board the aircraft.

Technical Malfunction or Catastrophic Event: Another possibility is that a technical malfunction or catastrophic event occurred on board the aircraft, leading to its disappearance. This could include failures in communication systems, electrical systems, or structural issues with the aircraft.

Inadequacies in Tracking Systems: The disappearance of MH370 highlighted inadequacies in the tracking systems used to monitor commercial aircraft, particularly over remote or oceanic regions. Improvements in satellite tracking and real-time monitoring have been called for in the aftermath of the incident to enhance the ability to locate and track aircraft in the event of emergencies.
