Probable cause:
The Board determines that the probable cause of this accident was that the flight while endeavouring to traverse a thunderstorm area encountered very heavy rain, divergent winds, and strong downdrafts that forced the aircraft to the ground. The following findings were reported:
- The flight was observed to enter and disappear in a thunderstorm,
- The aircraft crashed in an area where severe storm ground damage occurred,
- The US Weather Bureau Kansas City received the USAF severe weather advisories but considered their forecast in effect at the time to be adequate,
- The weather forecast issued by the Weather Bureau and Braniff did not indicate the severity of the storm that was encountered.
