>> so what i would tell you is not, you know, in the air force sometimes we talk about don't get platform specific, right, so what we're talking about is monitoring the domain, and having domain awareness. as i highlighted, a couple of days ago, probably last week, we're continuing to learn more about this program, which enables us to identify and track objects, and so and thus ensure that we're continuing to protect our skies and airspace. >> and then real quick, first, do you and admiral kirby know the shape of this new object, and if so, what is sort of the reason for why you can't share its shape before it was shot down, and then separately, how is the recovery efforts of this new object downed over ice different from the one downs over the coast and water and are you using unmanned systems for the new object as well?
