All airports will get thermal imaging cameras to prevent wildlife-related plane accidents which costs an estimated US$124 million

South Korean authorities said Thursday that all airports in the country would be required to deploy thermal imaging cameras and bird detection radar systems in the wake of the Jeju Air crash that left 179 dead.

The exact cause of the Jeju Air crash remains unclear, and the investigation is complicated because the black boxes stopped recording four minutes before impact.

The fire broke out in the back of the cabin, officials said. All 176 people on board, including passengers and crew members, were evacuated, some with minor injuries.
