The pilot who was lucky like that maybe the only one of the word. He was a doctor whose name was Rob Fraser. He was 47 years old. Oneday he flew a small plane "piper comanche" that had four seats and machine form runny in the middle of Cancas to Topeka in the morning. That town was far to the east about 255 kilometers. Suddenly, the exhaust gas was leaked and then the carbondioxide came into the plane.
