Using System Theoretic Process Analysis: Evaluate this scenario "The airline has an electronic gate-reader to record the passengers as they get onto the aircraft. Consider this device as well as any other factors you might think of in your analysis. Your risk is having passengers on board the aircraft when on the ground without the minimum required cabin crew, and a second is an unauthorized person getting aboard the aircraft without being stopped.
