white thing in the sky except for a couple of military planes flying around it, and it was over warrensburg. >> so when you saw it, there were actually military planes flying nearby it? >> correct. there was at least one or two. you know, they weren't very far from it. just kind of keeping surveillance on it. from what i know, a refill plane, but there has been planes currently trying to track it as there is right now down in southeast missouri. >> when you took these photos, how far was the balloon -- do you have a sense of what altitude the balloon was at? >> well, of course you know being an avid photographer of planes, it was much higher than your standard planes, at least 50-60 thousand feet. even the size of it, you could barely make it out to the naked eye. >> the military said about 60,000 feet. so you could see it with the naked eye? >> correct. you could see the actual balloon, and if the sun was shining just bright enough, you could catch the glimpse of the solar panels, whatever it is that's flying on the bottom of the balloon glaring off it. >> and were other people around you?
