Détails:
At 10:00 PDT Saturn Flight 14 departed the Alameda Naval Air-Station for a cargo flight to Wilmington, Delaware with an en route stop at Indianapolis The flight was uneventful before it reached Springfield, except for a deviation to avoid weather over Colorado. Shortly after a deviation to the right to avoid weather, the left wing separated from the aircraft at about outer wing station 162. The aircraft rolled and yawed violently, and shortly after the left wing failed , the right wing failed outboard of the no. 4 engine. The aircraft descended at a steep angle and crashed.

Probable Cause:
