What I see? You can watch it ten times like I did.
I see a object that is probably no more than 30 ft above the ground and about the size of a dishwasher. Speed? I'm guessing 25-to-35 mph...max (maybe less).
Anything within the Pentagon like this? No. Russians? I'm mostly saying no. Chinese? I'm not sure about.
Collecting data? If it lingered, then I'd say it was collecting phone/radio data. Photographic summary? You'd have it at 10,000 feet.
Alien? Well....no one can be sure.
Just running around a war zone...for alien data collection? For what? Doesn't make sense.
Worth viewing.
