believe the attack on Prezwodow, Poland was actually intended for cross-border transmission power line located at  50°24’38.93″N  24° 1’0.11″E.A cruise missile simply followed the power lines up into Ukraine and kept going after it missed its target.I do not believe an S300 missile was involved in the event because the missile would be going the wrong way. Surface to Air missiles expend all of their energy in the first few seconds of flight and do not have the ability to execute a U-turn.It is possible, however that a cruise missile may have been shot down if coming from Belarus, although that would mean the intercept was performed over Poland. Naturally, that would mean that Russia is using Poland as a corridor for missiles, which would be a bad idea.
