Braniff International Airways Flight 352 was a scheduled domestic flight from William P. Hobby Airport in Houston, Texas, United States to Dallas, Texas; on May 3, 1968 a Lockheed L-188A Electra flying on the route, registration N9707C, broke up in mid air and crashed near Dawson, Texas after flying into a severe thunderstorm. It was carrying a crew of 5 and 80 passengers. There were no survivors. Investigation revealed that the accident was caused by the captain's decision to penetrate an area of heavy weather followed by a structural over-stress and failure of the airframe while attempting recovery from loss of control during a steep 180 degree turn executed in an attempt to escape the weather.
