  1. The failure of the display piece suppressor looks like it was put into a standing wave by the gasses. That would be a stress on any jacket put on the suppressor. In all the other suppressors, there are more channels for the gasses to move through and to dissipate the kinetic energy of the gasses. The muzzle end of the display suppressor did not have any baffles for the segment that failed. It seems to me that more baffles throughout the suppressor is the solution, and it would act like when marching soldiers break step over a bridge: it prevents energy from finding a resonance point that makes a standing wave. A standing wave grows stronger and stronger the more times it is allowed to resonate, and standing waves can destroy muzzles, bridges, and even the plaza of the MGM Grand Hotel back a few decades ago.

  2. Step 1: [beginning of complicated equation]... Step 2: Then a miracle occurs... Step three: [end of equation] Expert reviewer, "I think you need to be more explicit in step 2."

  3. ​ @SpeedRacerXM5  Every time a spacecraft at NASA failed and public opinion was queried should we continue to go to space or not, the resounding answer was yes, let's continue to go to space. Ad Astra per Aspera

  4. As an avid space fan and regular citizen, I urge every engineer, physicist, aerospace employee, STEM expert, and rocket scientist to communicate like this from the CEO down to the QC inspector and back up to the CEO. Mom was a QC employee at TI checking diodes. She knew that the Apollo 1 disaster involved a faulty diode. She made sure that every diode she checked was as good as it was required to be. No diode on her watch was going to cause any more deaths. Mom was on the front line with manufacturing: the buck (of the diodes) stopped with her. Set hard and soft limits for temperature and weather for rocket launched. There are reasons for hard limits like for O-rings. Freeze them and they fail like on the Challenger shuttle. An astronaut these days might not need to do Calculus, but being an expert at their spacecraft is so important. (but don't forget algebra)
