Reports Report 755l (Event 755-2020)

Observer
Name Ryan M
Experience Level 2/5
Remarks I would be very interested in any information you can find on this event. I live directly across the river from Portland airport (PDX), and it would have been visible from the control tower. With the Air National Guard also stationed there, is it possible they would have some documentation of the object?
