Korea's Aviation Safety Ranked First in World
When it comes to air travel, Korean airliners may be the safest way to fly.
The UN's International Civil Aviation Organization says Korea ranked first for aviation safety so far with a 98.89 percent performance rating by international standards. The organization's rating was introduced in 1995 in the wake of a rising number of accidents in the early 90s.
The UN organization still has about 70 more countries to evaluate before the ranking is complete.
