Aviation Security: Historical Attacks and Countermeasures

A Retrospective View of Crimes and Terrorism in Aviation

Types of Attack

  • Three “fundamental” types of attack on aviation:
    • Hijacking (skyjacking) aircraft
    • Bomb placement in aircraft
    • Airport terminal assaults
  • Types of attack have changed little over time, but motivations, methods, and purposes have changed.
  • Now we should add “airplane as a weapon” to the list above.
  • Lethality and damage to society have expanded enormously.

Aircraft Safety Systems: Enhancing Flight Operations

Aircraft Safety Systems: Enhancing Flight Operations

Principal Risk Elements to Safe Aircraft Flight Operations

  • Loss of power
  • Loss of control
  • Stopping
  • Failure of aircraft structure
  • Aircraft fires
  • Mid-air collisions

Jet Engine Safety Contributions

  • Major increases in power, especially at high altitudes
  • More power available for engine failure situations
  • Much simpler controls = fewer opportunities for human failure
  • Ability to cruise at high altitudes, above most bad weather
  • Ability to climb quickly through bad weather
  • Dramatically

Aircraft Certification Standards and Airworthiness Compliance

Means of Compliance (MoC)

  • MoC 0, Statement: Direct Answer. Applicant declaration, normally supported with a short rationale, which shows compliance with the requirement.
  • MoC 1, Description: Descriptive document or reference to a document including the drawings that show compliance with the requirement.
  • MoC 2, Analysis: Documents with calculations and analysis that show compliance with the requirements.
  • MoC 3, Safety Assessment: Specific analysis prepared to show compliance with Safety Requirements (

Aviation Security: Threats and Acts of Unlawful Interference

Understanding “Unlawful Interference”

“Unlawful Interference” encompasses a wide spectrum of acts, ranging from moderately disruptive behavior to mass terrorist attacks. Examples include:

  • Vandalism of airport facilities
  • Air rage
  • Threatening flight attendants
  • Drug smuggling
  • Cargo theft
  • Bomb threats
  • Sabotage of aircraft/NAVAIDS
  • “Simple” hijackings
  • Fatal hijackings
  • Aircraft bombing
  • 9/11 mass attacks
