Every 2.5 seconds, somewhere in the world, a Boeing 737 takes off or lands. The Boeing 737 one of the world’s most popular planes, as well as one of the best-selling. But is it also plagued with dangerous structural problems? Last April, a Boeing 737 taking Southwest Airlines passengers from Phoenix to Sacramento had to make an emergency landing when part of the plane's body ripped, leaving a 59-inch hole in the roof of its cabin. It wasn't the first such incident to take place in a Boeing 737 — and a new investigation suggests it might not be the last.
