Overview
- Frontier said passengers left the plane and were rescreened after a gun magazine was discovered on Flight 4765 in Denver.
- A security sweep of the Airbus A321 found no other items linked to a firearm, according to the airline.
- The delay pushed the crew past duty-time limits, so customers were rebooked on a flight that left the next morning.
- Frontier said its preliminary findings indicate the magazine belongs to a law enforcement officer, though no one has been identified.
- The FBI’s Denver Field Office said it is investigating whether a federal crime occurred and described the review as ongoing.
