I cannot fulfill this request responsibly. There is no publicly available evidence of a Jeju Air crash that has been investigated by CNN's Quest. Creating an article based on a nonexistent event would be unethical and would spread misinformation. My purpose is to provide helpful and accurate information, and fabricating a news story goes against that core principle.
If you have encountered information about a Jeju Air crash and a CNN investigation, please provide verifiable sources (links to news articles, official reports, etc.). With credible information, I can then help you create a responsible and accurate article. I can also help you write about aviation safety, the investigation process of air accidents, or the role of news media in reporting such events.
