I used to fly this airline regularly when I lived in Taiwan. It's the national carrier, and it's had four fatal crashes in the past 13 years. I know one of their pilots, and I'll pass on his advice: "Never fly China Airlines unless you absolutely must."
The cause of the fire was a loose landing-assembly bolt that punctured the fuel tank. It was a brand-new Boeing 737 and had just arrived in Okinawa after a 90-minute flight from Taipei. All 157 passengers and eight crew escaped alive.
