I can't remember what user was familiar with military flight operations/training, but on Monday I believe, when we were tracking the medical helicopter (which turned out to be unrelated..) that user were giving info on what certain planes might be doing in the areas around Tucson:

I'm asking because right now there is a US Army helicopter (GOON93) circling the mountains north of the Catalina Foothills and it was previously circling on some mountains further north of there (it took off from Pinal Airpark). It doesn't look like there's much up there other than a small ski resort and they weren't circling that but hiking trails and some canyons (and the furthest right circling is around some old mines up in the mountains).
Could be for a missing hiker or training or anything else, but thought it was interesting that it was military and it wasn't taking off from any bases nearby which I think is more common for training ?
