Who is authorized to carry firearms on a flight?

The authorization to carry firearms on a flight is specifically designated to individuals tasked with ensuring the safety and security of the aircraft and its passengers. Federal Air Marshals are highly trained law enforcement officers who work undercover on flights to prevent and respond to any threats. Law Enforcement Officers may also be permitted to carry firearms when on duty and in accordance with federal regulations. Flight Deck Officers, typically representing specific airlines or under particular programs, are also authorized to carry firearms to protect the cockpit and crew from threats.

Other options provided do not align with the current regulations governing air safety. For instance, flight attendants and ground crew do not have the authority to carry firearms while on flights, as their training does not encompass armed security responsibilities. Similarly, while pilots have significant responsibilities for the operation and safety of the flight, only certain pilot groups, like those in specialized programs, may carry firearms under strict conditions; they are not a general category authorized like the individuals in the correct answer. Security personnel may have roles related to airport and flight safety but do not generally carry firearms onboard unless they fall under the categories outlined in the correct option.

Therefore, the individuals listed in the correct choice hold a specific mandate and specialized training essential for maintaining security during flights.
