Approximately 23 minutes into the flight, while cruising at an altitude of 24,000 feet, they were about a fourth of the way to their destination. But then, a section of the aircraft’s roof ruptured with a thunderous explosion.
From the cabin to nearly the plane’s wings, the roof of the plane had been blown off in a violent decompression. In the process, 58-year-old flight attendant C.B. Lansing, who had been standing just under the roof that flew away, was ejected from the plane. Her body was never recovered.

This flight is why I always wear a seat belt on a plane. Always.
