I seen one similar to that in 1976 over the Columbia river daylight up close it was checking the Portland airport out. It was just sitting there tipped in that position like in the photo it was gray and then it tipped towards this and you could see the cockpit on top it had an orange reddish cockpit.on top tree top level it was a eye opener we accidentally snuck up on it. We went under Highway 14 at 164th St. exit popped up on the other side to get up onto Highway 14 that’s when it tipped towards us. It picked us up when it’s radar?
