Study the roll thruster plums as I think they locked up in gimbal lock failure….

Jim 

 After reviewing you efforts I realized  I had a Soyuz launch sequence error which I have finally gotten around to correcting

Sustainer core second stage shut down

Third stage start fire in the hole ignition

Third stage  full power separation with second stage core sustainer jettisoned

Third stage Inter-stage skirt jettisoned in three parts

11

Start pitch & roll programs at various points through the flight

322, 364 

421- 441-464, 

 

<5,050?

5,894

<1,050 

 

178-182

 

1,879

You will notice the failure around 424-425 seconds is during the roll and pitch  programs operations of the third stage during its flight

 

Pay particular attention to the sequence of operations that are entirely consistent historically with the earlier Soyuz booster flying at lower altitudes which the more powerful new ones fly somewhat higher lofting but it comes out near the same at the end of the profile  flight to orbit. Differences being the payload and application sequencing for the launch requirements.

 

For what it is worth

 

Peace to you and yours,

Pat

I’ve been working to document the Meridian 5 launch failure of 2011 Dec 23, including the visual phenomena and terrestrial dispersion of debris. Review draft 2 is available here [I’ve already been collecting helpful typo lists and corrections to my math of ‘shadow height’]:
