The rapid pressurization of gas within the segmented rocket motor acts against the o-ring and pushes it to block any flow passage. So it is correct to say that one would not expect to see hot gases touch the o-ring or burn them, as that would imply hot gas being able to flow.
If they saw hot gases then a complete seal was not accomplished. Thanks
On the 34D. I don't recall the investigator who I know personallly ever mentioning putty as a cause. Is that really documented?
