It's shit like this that shows "duck and cover" makes sense. That stuff wasn't supposed to keep you safe from a nuclear explosion, it was to keep people from getting shredded by broken glass by the shock wave outside the blast zone looking at the bright lights and sparkles through a window.
I don't know how many people have ended up seriously injured trying to get cell phone footage of this conflict but I imagine it is a lot. Seek cover you morons. Those strike fighters aren't dropping love letters. Ruskies are using thermobarics and those are no joke.
