It's not inevitable, as evidenced by all the other accidents that have been... evited. You just don't hear about those. (Yes, evited is a word, it's just weird.)
I believe the OP here meant not that this specific incident was inevitable but rather that the death of a private astronaut at some point was statistically inevitable.
> current spaceplanes have the capability to fly and land autonomously--Boeing X-37, Dream Chaser, even Buran was fully autonomous and that was 25 years ago. There is simply no excuse for Virgin for being sloppy.
The point being there shouldn't have been human pilots in those seats in the first place.
It is demonstrably avoidable, there is zero need to risk human lives when doing testing these days. This is why Sierra Nevada's Dream Chaser has the capability to land autonomously and is precisely why when it had an accident in 2013[1] nobody was hurt.
