Ohio Man Sentenced to 30 Months for Threatening Passenger with Box Cutter on Flight

The incident, which occurred in November 2022, led to an emergency landing and highlighted security lapses at TSA checkpoints.

William Liebisch, 43, from Cincinnati, was sentenced to 30 months in prison after threatening to stab a fellow passenger on a Frontier Airlines flight.
The flight, en route from Cincinnati to Tampa, was forced to make an emergency landing in Atlanta following Liebisch's threats.
Liebisch managed to board the plane with a box cutter, despite TSA officials removing the blade, by concealing a spare blade in the handle.
Passengers and flight attendants played a crucial role in subduing Liebisch and preventing further escalation of the situation.
The incident has prompted the TSA to conduct additional trainings to prevent similar security lapses in the future.
