bearfoil, I have long contemplated an upset or intentional rapid dumping of altitude with the crew in control or back in control before the splash. They may have been trying to goose the engines hard enough to get them back flying after the altitude loss and simply ran out of sky. I'm not sure there is near enough data to fully support that scenario. I am not sure there is enough data to rule it out. That's why I've not harped on it.
