CFIT accidents are the most severe aircraft accidents. These kinds of accidents occur when an otherwise airworthy airplane is inadvertently flown into the ground or water. The number of fatalities per accident is extremely high as compared to any other type of accident. They also generally result in complete destruction of the airplane. If CFIT accidents were to be completely prevented, approximately half of the worldwide fatalities in aircraft accidents would also be prevented. CFIT accidents have a high leverage for safety improvement.
