Very interesting if MGL is Mogul in these posts, it looks like either he is moving, or something airborne is moving against him…. nothing out of ordinary over DC to first look. I checked MGL airport (Dusseldorf/Moenchgengladbach, Germany - Nothing obvious there). Roof and Ground batteries exist at WH so these may be activated to counter something in controlled airspace….. all speculation at this point, but digging like mad right now
