Abstract
This chapter is devoted to delivering the fundamentals of aerodynamics. In this view, a perfect understanding of the principles of aerodynamics can assist to investigate how the MH370 crashed in the Indian Ocean. Bernoulli's principle is the keystone to understanding the aerodynamic mechanism of MH370. This chapter addresses a new theory of the MH370 crash based on the turbulence impacts on the airframe. In the circumstance of the MH370 air crash, the dynamic processes are addressed to reveal how the MH370 was uncontrolled.
