An unruly passenger was reportedly arrested in Hong Kong after allegedly trying to open an airplane door mid-flight on a Cathay Pacific plane from Boston.

The frightening incident went down on Wednesday … fortunately, no passengers or crew members were injured, and the plane landed safely Thursday morning.

The airline tells TMZ … “Our cabin crew immediately attended to the situation, inspected the door to ensure it was securely closed, and reported the incident to the relevant authorities and the police.”
