Eight years later, we are still waiting for an onboard camera...

 

Has the despair of some of us been heard by Arianespace? They have just released a recap video of the 16th launch and a short view from an on-board camera is visible at 1:12.

 

 

 

3139 days. It took 3139 days to share a sight provided by most other launch providers.

Yeah, solids have low enough ISP that more stages make sense. Also, since it is hard to control their thrust, you would have issues of too much acceleration if you had a solid stage that burned too long.

But still, it's an issue.

However, I have to admit that the solid stages seemed to not be the problem here. It was the liquid stage that failed.

Yeah, there are a lot more ways a liquid-fuelled engine could fail compared to a solid, making them more reliable for the most part. Of course, that's unless they're huge, segmented, and right next to a giant tank full of liquid oxygen.

more details on the cable issues below,  it wasn't an issue with the cable connections themselves, it was that they were the connectors for the opposing actuators on the engine gimbal, leading to loss of attitude control.  this is something that absolutely should have been caught by even the most basic preflight tests.

I would say that maybe the cables should have been designed so that they can't be connected to the wrong sides, but we've seen often enough that even such foolproof engineering can be defeated by determined fools.
