Hi, Andres, this is Paul. Happy to cover sort of the DoD work. I mean, just to put to give you guys a little bit of color, we're obviously very much focused on delivering on the aircraft that are required for that contract and really beginning to prepare ourselves for the operations on base down at Edwards. So, we mentioned that the aircraft that we rolled off the production line is going to be the first aircraft that is delivered on that contract. But we've also, already put a number of Air Force pilots through our pilot training program. They went through both the, sit down, portion of the training, the simulator training, actually did remote piloted flights of our aircraft at our facility. So, that was a really great trial run of the same sort of pilot training program that we are eventually going to have to roll out on the consumer side. So, we were happy to check that box. And then lastly, we've even started work down on Edwards, in terms of setting up the charging infrastructure, that's going to be required for operations. So, on the Joby side, we're full steam ahead in terms of being able to deliver on the contract, as soon as possible. A number of the aircraft that are sort of sitting behind the aircraft that we rolled off the line are also designated for Edwards. So getting to those milestones is something that we are squarely focused on. And I think the reason is really twofold. One, is obviously the opportunity to generate revenue, in support -- across that contract. But second, and even more importantly, it's really the first opportunity for us to deliver a product to a customer, and have it operate in the real world as opposed to on our test facility. And there are tons of learnings that come from that, already things like the pilot training, the maintenance profile. We want to make sure that we get all of those learnings, as soon as possible with the largest number of aircraft. And that's the way that we're sort of directing our efforts here.
