Phil- In the referenced thread, the pilots _knew_ they had a catastrophic engine malfunction. They did not know, however, that the engine had departed the airframe. In a massive engine failure, especially uncontained ones, all the engine indicators ie: temps, pressures, speeds, EPR, etc, will likely go off-scale. So in some cases, the crew may not know if the engine failed completely and remained attached, or if it actually departed the airframe. -Reminds me of a memo I once got..."the aircraft was passing through 8000 feet, when the Number 1 engine flamed out. A normal cross-start was made, and the engine returned to base."
