Suppose someone shoots down a missile from orbit, or something that causes a pressure wave. It doens't matter what, but lets assume:
The explosion that causes the pressure wave does not kill the person inside (as in if a nuke goes off, this question is pointless if the person in (2) below would be vaporized).
The glass is blown inwards into, say, the house, where a grown adult is standing. We can assume it's the standard glass we have in our houses nowadays.
How likely is someone to die or be permanently damaged from (2) above (ex: vision loss, amputation, etc), if we assume (1) does not kill them? I guess one could say there's always a non-zero chance because maybe a shard of glass could lodge itself in your neck and slice a critical artery and you bleed out.
Or maybe better, what if there's no medical services around? For example, if a missile from orbit does severe damage to the city, hospitals would be flooded and any affected characters in the story could not get medical help.
However, I am unsure how likely it is. For example, if I was to have someone die, the last thing I want is the reader to say "that would never happen" and lose immersion. I do not know if someone would be full of glass, and in a very painful state and susceptible to all kinds of problems after that (such as infection, lots of pain, etc).
From my research on explosions like grenades, shells, etc, it seems like its the pressure that tends to kill the most. Not much seems to be said about the fragments. Though they do seem to be dangerous, there was less information than I'd like and I was not able to evaluate whether the concept of being near a window of glass exploding inwards is very dangerous or not. I assume it is, but I'm not sure if I'm also grasping at straws and/or thinking of a scenario that realistically would not happen.
While this is not hard sci-fi that I'm writing, I don't want to do something unrealistic.
