He's an absentee landlord, a kid with an ant farm. He doesn't care, and doesn't lift a finger let alone give any grace....
However, since it could happen to anybody, I'd go with folks in glass houses shouldn't throw stones....
better yet, let he who is without sin cast the first stone.

Back to the topic at hand. Glad the crew was able to recover from incident. Stay safe out there.

He gave us free will for one purpose, to choose to love Him. Let’s not make it more complicated than it is.
But I agree with your last statement. It applies in this incident as well as life.

My two cents ...
Passing around 3,200 feet the airplane had a approximate 3,500+FPM climb. That is significant. I bet the FMAs went into altitude capture mode and the autopilot stopped looking at speed and pitched for the 5000ft level off and the AP slowed them down while the Flaps had been retracting. I've seen it before on both the 777 and other Boeings.

That's actual a natural thing for many pilots, the mike tends to stay keyed if you suddenly have to divert attention while talking.
I'll give him credit for prioritizing PM duties over radio technique.

I have never flown the 777 at a weight heavy enough that the clean flap maneuver speed is above 250. Will the VNAV schedule a speed above 250 below 10,000 at the acceleration altitude?

I would not give too much credit to Flightaware climb rates. It seems that 3500+ FPM climb rate is a bit high for a heavy 777 at 240 knots or so.
