Is it possible to say "succesful failure" without sounding like a PR person doing a damage control?

I mean, lets imagine that "test early, test often" is a good engineering practice (it probably is, but lets do not discuss it here, just assume it as a premise instead). Lets imagine that SpaceX blowed up its rocket to gather more data. Is it possible to say "it was a succesful failure" without it looking as a rationalization?

It is an important question, because if the answer is "no" then your observation is not informative.
