One tough old Lockheed machine.........
An RAAF Orion went into the lagoon in the Cocos islands due to the wing structure not being constucted to manufacturers specs. This led to a re- winging program. Not related but interesting none the less.
An RAAF 707 also went down off the coast of East Sale, Victoria, Australia in 1991 after what was described as a "Sudden and extremely violent departure from controlled flight" during double assymetric training. All five crew were killed. It seems this is not a unique incident.
