What are the main reasons behind a flight crash these days?

A flight crash can happen for many reasons, even with modern airplanes and high-tech systems. One of the most common causes is pilot error, like poor decisions or missed signals. Mechanical problems, such as engine failure or broken parts, can also lead to serious accidents. Sometimes, bad weather like storms or turbulence makes it hard for pilots to keep control. In rare cases, a flight crash may be caused by intentional acts like sabotage or hijacking.
