All right, let me take that and I'll start with the drones. I think drones is an area where, again, we see tremendous long-term opportunity. Near term, there's a couple of different issues that have slowed, that are sort of, I think, were pre-inflection points, shall we say. So on the outdoor drones, there's a growing interest in drone as a first responder, namely -- today the way they deploy drones is the police drive up in their patrol car, then they open the trunk, they take out the drone and they fly the drone around. That doesn't give nearly as much benefit, right? Cause you've already got to get on scene to use the drone and then frankly from an officer safety perspective it's not necessarily great to be standing around staring at a drone controller. I think where the market wants to go is this idea of drone as a first responder where the drone is deployed from a fixed facility, flies to the scene and gets there before officers can. That started in Chula Vista, California. Shout out to Chief Roxana Kennedy there who really started this. We're seeing that, it is in the early stages of an exponential doubling pattern. Every year we're seeing about double the agencies doing drone as a first responder. It went from single digits to now in the tens of agencies doing it. In order for that to really take off, we need a little more clarity from the FAA on agencies being able to fly beyond visual line of sight, to be able to fly the drone safely. Today, if you want to fly drone as a first responder, most of the time you have to have a police officer standing on the roof under an umbrella, watching the drone fly into the distance. We have through one of our other partnerships with Dedrone, that is the world leader in drone tracking and counter-drone, we've invested in that. We've partnered with them. Dedrone gives you the ability, the NFL stadiums use it to track all the drones around NFL stadiums. And Ukraine is buying a ton of these to track drones for obvious reasons. We have some pilots we're doing where Dedrone is coupled with drone as a first responder. So instead of a human being watching into the distance, they can't see a drone beyond a couple hundred meters, we can actually track those drones in the airspace with this integrated solution. And we think that is going to be foundational to really letting drones really grow. Actually, let me pause for a second. I just may have had a technical correction for me on the growth rate. I guess we're going to be conservative. It was more than a doubling this year, but it was off a small base. So again, we're seeing really early exponential growth in DFR. Now when we think about indoor drones, Sky-Hero, when we acquired them, so one of the downsides of being a big company is we have lots of lawyers to make sure that we're very compliant and that's obviously a good thing most of the time. But for example, we discovered that Sky-Hero had some challenges in that the bands of energy they were using for RF transmission to get through the walls to be able to fly indoor effectively were outside of the acceptable bands under the FCC here in the United States. So we've had to actually pause selling on a temporary basis while we are working to get approval from the FCC and an exemption on being able to sell those to state and local in the US. But again, we didn't buy Sky-Hero for the near-term revenue. It's really about the relationships they have with the world's leading SWAT teams and tactical users, and we believe that's the foundation on which we can build transformative new capabilities. So part of it is just kind of getting, with Sky-Hero, now they're part of a bigger organization. The good news is, we've got both teams focused on international legal compliance. So we're kind of upping their game from a compliance and legality standpoint. Meanwhile, they're bringing their, I would say, young scrappy innovation. I mean, these guys built a profitable drone business with a very small team. Not many people have done that. And I'd say the magic is happening. They're working with our design team. And I'd say over the next couple of years, I'd say maybe a two to five year horizon, you'll start to see some pretty mind-blowing stuff coming out of our indoor tactical drones as well as our outdoor DFR. I think those are the two biggest segments, being able to fly outdoor drones without humans on site and then being able to go into buildings and use drones in the most dangerous situations.
