have with this spy balloon. perhaps in the area of signal intelligence and that sort of thing. what do you think they might have been doing other than taking pictures? they can take pictures with satellite. >> yeah, they can. the resolution is very good and the pictures are good. low-power manipulations you can't pick up from a satellite. the lower altitude. also, if they're making any changes in those bases, they're done when the chinese satellites are not overhead. we do that all the time. if we're going to move things around, you wait. so if they have three or four days over one of these sites, they can get a good view of it. it's not a game changer. if you're sending a message to washington, we're going to spy out. we know what you're doing. one of these balloons is very effective. >> all right. very interesting. great to see you. thank you for your time.
