A 45-year-old woman in China made approximately $420,000 by buying insurance on flights she predicted would be delayed, using over 20 different identities to avoid detection. She used her knowledge of the airline system to selectively take out insurance on flights that were likely to be delayed. The woman was eventually arrested and the insurance companies have since fixed the loopholes she exploited. The incident raises questions about the nature of insurance and the intentions of those who purchase it.
