How does aircraft design contribute to passenger survival during emergencies?

Aircraft design incorporates multiple safety features that protect passengers during emergencies. Engines are designed to shear off with certain force to prevent fire and stop spinning blades from becoming dangerous projectiles if the engine ruptures. The wings are engineered to separate from the airplane during high-impact events, absorbing force that would otherwise be directed toward the passenger cabin. These structural elements work together to maintain the integrity of the fuselage where passengers are seated, allowing people to survive what could otherwise be catastrophic incidents. The deliberate engineering of breakaway components helps dissipate energy during crashes while preserving the survival space within the cabin.
