Investigations in Respect to Accidents of Airplanes

The process of flying airplanes successfully is the result of a total of physical and chemical reactions at balance circumstances. As much as the processes are controlled properly, the flight occurs successfully. This research focuses on the physical properties of materials in different conditions that lead to changing their properties towards undesirable aspects and how to maintain the quality of the original properties of the material used in the airplanes by maintaining the conditions that the material needs to keep its original properties. We witnessed several airplane accidents and investigated their causes by investigating the conditions surrounding the airplane before and during the accident, focusing on the date and time of the accident to determine the atmospheric conditions such as temperature, air pressure, and air humidity, as well as the changes in torque generated in the wings during flight during the malfunction of one of the engines and efficiency jet engines, as well as contractions caused by the reduction in the temperature.
