CRS-7 started as a failure of the second stage, at much higher altitude. The cloud of gas from the ruptured upper stage tanks would have obscured much of what was going on with the booster.
It was a very different "failure", which would naturally look different.
- _Microft 7y agoThe overpressure from the burst helium COPV ruptured the second-stage tanks and spilled the contents. We didn't really see clouds of unburnt fluids or gases this time, it was an explosion right from the start. That's what I meant when I said it looked different this time.
- JshWright 7y agoRight, but your explanation for those differences seemed to be (based on the context) related to whether or not the FTS was triggered.
- _Microft 7y agoYes, I actually meant to say that the sudden explosion did not look like CRS-7 which had this spilling-a-dewar look and guessed that the AFTS might have been involved. It was really nothing more than a wild guess.
