This is the terrifying moment a plane crashed into the Pacific Ocean during a storm as the pilot yelled "we're too low!"

Crash investigators have released shocking cockpit footage showing the final seconds before the plane dived head first into the the ocean off the coast of Papau New Guinea in September last year.

The Air Niugini Boeing 737-800 aircraft was preparing to land in stormy weather but missed the runway by 1,500ft, sending the aircraft heading straight for the Pacific Ocean.

One male passenger died while nine others were injured in the crash.

Dozens of other survivors paddled to safety.

Moments before the plan sunk into the waters, the co-pilot was heard shouting to the captain: "Too low! We're too low! We're too low!"

Seconds later, the footage cuts off as the plane appears to have dived several feet into the Pacific Ocean.

Crash investigators noted the pilots had ignored many "pull up" warning signs and warning lights as they prepared to land, according to a Papua New Guinea Accident Investigation Commission (AIC).

The report stated: "The crew were fixated on the task of landing the aircraft and did not notice the visual PULL UP caution alert at the bottom of their PFD.

"Therefore, they (the crew) did not take any positive action to arrest the high rate of descent and avoid landing in the lagoon. In fact, neither of the pilots were aware of the rapidly unfolding unsafe situation.

"The investigation found that the crew had received similar aural alerts on previous approaches in visual conditions where the aircraft was safely landed.

"This would have contributed to the perception that the alerts during the accident approach were nuisance alerts, and therefore disregarded them."

The pilots were said to have missed "pull up" warning signs before the crash

The pilots were said to have missed "pull up" warning lights and continued to attempt landing despite the stormy weather.

AIC chief commissioner Hubert Namani said: "Both pilots were fixated on cues associated with control inputs for the landing approach, and subsequently were not situationally aware."

Thirty four passengers and 12 crew members managed to swim to safety.

The passenger who died was found not to be wearing his seat belt and suffered severe head injuries.
