we've done it in the past during standoff situations when there aren't any civilians in the house. we usually use a really small, cheap drone, usually some oddball brand rather than a dji. we just need a decent enough video feed to get a visual of the situation. there's a very good chance that we'll lose the drone.
for our training we're using our older fleet of phantom 4 drones and some air 2 drones. we were going to take the inspires, but we scrounged up more phantom 4s. we'll work on techniques like verbally identifying where you are, going up and down stairs and turning corners without seeing drone or the space we're working in. the newer pilots will make a few runs through the house and identify what room they're in or identify where an object is. the more experience pilots help the newbies, but they get to go in later. we'll play hide and seek with a few of the drones in play at the same time. so not only do you have to go find something, you have to avoid other drones without knowing exactly where they are. it can get rowdy.
flying indoors in tight spaces is one thing. walls don't have those tiny little moving branches. i hate flying in the woods, that's a scary situation, esp. in the densely packed woods that we have on the east coast and what you have in the pnw. we usually fly above the treetops with thermal when we need to search the woods.
