Soyuz MS-10 abort caused by sensor failure at booster separation

Quote:
Russian investigators have concluded last month’s Soyuz MS-10 abort was caused by a sensor failure on one of the four Soyuz FG boosters. The sensor, which triggers LOX valves to vent on the top of the booster – allowing them to cleanly depart from the core – resulted in the booster sliding down the side of the core and rupturing it tank, causing the Soyuz FG to fail and the Soyuz MS-10 to conduct an emergency abort. A press conference blamed an “error during assembly” of the launch vehicle as the root cause.

Finally it is made public!
Very dramatic, even in slow motion.

Slow motion? The video feels like it is twice the speed...

Yes, it is sped up, but I watched it in slow motion.

Apparently, it was a sensor failure.

Yes, according to the Facebook posts of Roskosmos, it was a 6.5 bend in a mechanism.

(...)Also, according to the official timeline, the separation of the Descent Module, SA, from the escape stack took place at T+158.75 seconds in flight (121.57 + 37.18 seconds). However, the crew of Soyuz MS-10 reported that the separation had taken place at 11:42:50 Moscow Time which is equal to T+154.5 seconds in flight.(...)

Yeah, there is an obvious cut in the footage. The question is *why*? I can't imagine that there's anything in the missing frames more embarrassing than the separation failure itself, much less more embarrassing than having blatantly missing frames from the video. If there was something they really didn't want the world to see, they could have not released anything at all, and if the missing frames were caused by a technical fault (unlikely, given the photo above) they could have explained that. All removing them does is make Russia look paranoid and incompetent.
