Ukrainian drones have successfully hit a factory making Kh-101 and Kh-55 cruise missiles in Smolensk. In response, the Pantsir SAMs system guarding the facility did what they do best, and took out a nearby apartment building. Must have thought it was a civilian airliner. Seems to me that all Ukraine needs to do is send a bunch of balloons across the border and the Russian air defense systems will self destroy all the infrastructure around them.
