Yes, I think it's -- it may seem counterintuitive, but it's really around data architecture, right. Whereas, most people talk about the hardware, the acquisition of data first, but because Louis, when he designed the system, designed it from military perspective, he designed the network and the software first. And then how do you acquire it through whether it's a lidar system or a combination of lidar and other sensors. And I think that was refreshing and very attractive because in most aerospace and military situations, they're actually trying to solve a problem first, which means it's about data. Most people, maybe you wouldn't put it this where most people don't think about this, but at the end of the day, you can't be autonomous without making decisions. You can't make decisions without data. So, we're really in the data business, better spatial data faster. And that's really I believe what impressed our partners at Booz Allen, because they're the experts at AI and machine learning. And one of the challenges that they have as they've said publicly before is that, a lot of times people are bringing them in to build out this system, but they have to deal with whatever data that's being put through the pipeline and they can't change it. Well with us, our system can actually, it's a two way communication, they can actually ask for the type of data that they want. So, it's much more impactful in their perception stack because we together can actually acquire and preprocess data in a way that makes it easier for AI and machine learning to add value, to make decisions faster. So I think that's the first thing. I think the other thing is just that, we were -- we're adaptive. And I think that in the aerospace and defense, there's very rarely a one size fits all solution. And the fact that we could give them a commercial off-the-shelf hardware system that had the kind of performance envelope they were looking for yet, they could customize in software and on the sensor. I think that was also very attractive. So, I think data and adaptability of the operating system.
