Japan Airlines flight 61 from LAX to Japan was just pulling back from the gate, when its left outboard engine sucked an empty container that was being driven too close to the jet. This Boeing 747-400 has about 60,000 lpf thrust which can create a lot of sucking power. The container is about 5′ x 5′ x 4′ but looks quite small while parked inside the engine. The passengers had to be unloaded and the plane was taken for inspection.
