Just had a very quick go at Ngram but there are too many kinds of planes for it to show me what I want, I reckon (plane of reality, plane trees, woodworking tool, mathematical term, etc.).

TY. I had a go at it. I couldn't quite see what I wanted, but I suspect it's bc the HTE doesn't do it. I'll have a look at the Ngram viewer. I tend to use it to check what's more common now, but it's obvious it works the other around too now you mention it. 🙃

Found this! There's hope still for me. (referring to a post I hopefully published correctly a few min. ago as otherwise you're going to think I'm mad...)

I'm a newbie here and I don't know my way around, yet. The CIEP 2023 Conference feed I had joined is empty and I'm a bit lost...

So important that we are able to get a 2nd (3rd, 4th?) medical opinion. The other place said there was nothing else they could do.
