WSSS -
1. The CVR ends with the captain leaving the cockpit with the seat slid back and nothing substantial to suggest that he pulled the circuit breakers. The CVR is dual powered.
2. How did he manage to pull both circuit breakers without the copilot noticing?
3. The ATC recordings attest to the first officer being alive immediately before the high-dive.
4. How did the captain pull off the high-dive, unopposed? A struggle would have knocked off the autopilot, leaving a radar record.
5. Finances aside, what valid indications were there of the type of anxiety or depression leading to this supposed suicide?
The ValuJet 592 investigation is a CVR and FDR farce. The date is unimportant.
The Alaska 261 CVR data is conspicuously highly incomplete. Granted the final report isn't out yet. There seemes to be spin-doctoring in progress, focusing on the jack-screw, which couldn't uniquely account for the accident.
Again, my mind is open, but so are a lot of questions.
