Right now, there's no convenience filter for it (you can filter manually for anything and save it). Since this is suddenly becoming more of an interest for our (traditionally scientific) users, we'll look into it. No promises!
We are aware and while that is not our niche, we'd be happy to support that. Maybe a quick and dirty hack at least. But is there an authoritative list of miltiary aircraft anywhere? Without that it's not trivial.
Was hoping there was a military filter here. As that is my primary interest and I'm coming from adsb. I found a website that has a updated compiled list someone posted on Reddit. The list is way to long to post here but I do have a link .
