I think if you’re describing planecrash as “the single work of fiction for which I most want to avoid spoilers”, you probably just shouldn’t read any reviews of it or anything about it until after you’ve read it.
If you do read this review beforehand, you should avoid the paragraph that begins with “By far the best …” (The paragraph right before the heading called “The competence”.) That mentions something that I definitely would have considered a spoiler if I’d read it before I read planecrash.
Aside from that, it’s hard to answer without knowing what kinds of things you consider spoilers and what you already know about planecrash.
