 I met here in the middle of the exhibition hall of Intergeo 2022 in Essen. It's Chava, singer from H-Aero and of course I saw the H-Aero of course up here in the air. Hi Chava, how are you doing? Hi Denise, how are you? Thanks, I'm fine. Good to see you here. So you're again here with the H-Aero, the indoor drone. We already met at several intergeos for several years. You presented it first, I think four years ago, five years. It was five years ago at Berlin Hintermesser, it was let's say our first, let's say together. And since then we carry on every year, flying around for the intergeo, but also for the many different use cases and for the many different customers and the audience of Intergeo. Tell us more about your customers and the use cases, where the H-Aero is used for. So at the moment we could find out that in research and development, so it's more or less some kind of aero tip of technology what we have here, a computer in the state of suspension. Research and development, how that? Yeah, like when there are some PhDs, when some professors apply for federal funds, they used to do it more and more with H-Aero and therefore there is also a relatively high success rate. In funding from let's say the European Commission from the federal ministries or also from the regions in Germany. And let's say we sold the system to Voodafone in one of the last years, could survive also Corona. As you know the events went down a bit, so we could focus more on earth observation, geodetic research, agriculture, forestry. And the really advantages of this H-Aero is it's an indoor flight object, so you can fly over persons and yeah, so it has many use cases. Not only, yes, so we have three different flight modes, so one of the flight modes is free flight, indoor and outdoor. Of course there the weather must fit, the wind sensitivity is relatively high, but if we want to have a position holding, outdoor for example looking at traffic, then we can also have a tattered balloon with the same device, we just need to let's say manipulate it a bit. And then we can have it in the mode of a raft like an aerosol. And there we can fly huge areas with the wind collecting data like a satellite. That's really cool. So it's a cool thing that I saw five years ago, first time I interviewed you and it's still here and it developed so much. So if you're here around in the exhibition halls, look up because there might be an H-Aero above you. Thank you for joining us. Thank you so much.
