I've not been around for a couple of days so apologies for referring to a previous posts but I feel that there are a couple of points that need clarification:

I disagree. The EmLub system is designed to work in the case of total loss of MRGB oil. It is not a 'fix all problems' solution that can make up for the catastrophic failure of the main gearbox shaft. This was the case for REDW and CHCN.

Hmmm, I wonder which company operated REDW's gearbox before it had recently returned to EC for overhaul...? Yep, like you said, 'extremely lucky'.

This was Air France Flight 296. Due to the unexpected low height for the fly-past (30'), the aircraft engaged it's 'alpha protection' mode so that when the co-pilot selected TOGA power, the elevators did not respond to the pilot's command. This was to prevent the aircraft stalling because it was already being flown at maximum angle of attack. The outcome, like you said, was that rather than climbing away, the aircraft flew straight into the trees.
