Got this info from my airlines unofficial forum. Unofficial of course .
The initial bobble is from turbulence at 6200’. When the FO called for flaps 1, the captain accidentally hit the toga button. Toga didn’t engage until after flaps were set to 1, which then brought engine power to full, and started the initial pitch of 10 degrees nose up. The FO was startled, and shoved the nose forward... The CVR is startling, and baffling. The CA was pulling so hard against the FO that he sheared the pins on the stick and at that point had no control. They were IMC at the time. When they broke out into VMC, the FO said oh schit and started to pull. That was the round out you see. I won’t get into anything more until everything comes out. The records, the CVR, and what happened in the flight deck is truly shocking. They hit a negative 4 G dive initialy on the FOs push. All you hear is stuff hitting the ceiling and at one point a loud thud. They think the thud may have been the
JS hitting the ceiling and maybe not wearing the shoulder harness. Like I said, I won’t get into anything more about the background of how it all happened. This is the accident in a nutshell. The facts that will come out are shocking.
