MEDIUM SHOT DAMAGED SOUTHWEST PLANE

Medium shot of Southwest plane that made an emergency landing in Yuma, Arizona on April 1, 2011 due to structural problems. This caused the National Transportation Safety Board (NTSB) to make new requirements for inspecting some Boeing 737 aircraft in the -300, -400 and -500 series. The 15-year-old aircraft, which had logged 39,000 pressurization cycles, a measurement of the number of takeoffs and landings, made an emergency landing after a gaping hole in the fuselage opened above the cabin of the plane approximately 18 and a half minutes after it took off from Phoenix Sky Harbor Airport. The plane was headed to Sacramento, Calif.
