There has been a few questions lately asking for information that
really, only people who work with/for the OEM can answer definitively,
as it's not publicly available information.
It depends on what we want for this site: Enthusiasts, experts, insiders...?
My opinion is the site would benefit from attracting and retaining people from the aviation domains, to balance the high number of self-educated enthusiasts (a group I belong to).
On the other hand, I'm often filled with consternation when I see trivial questions reaching summits, and potentially interesting questions not upvoted. So maybe experts won't find a lot of interest in being ignored by the voters.
We have the possibility to change that it this is what we want. But these people won't come to explain the difference between groundspeed and airspeed.
What is the problem with leaving these very focused questions open? Even if we considered them having little interest... there are tons of unanswered questions with, IMHO, a really limited interest for this site.
Regarding whether a question can be answered, looking at these ones, I'm not sure we can know for sure.
