For example in this situation, warning could be issued to get away from windows and cover you in big octopus that will absorb all glass shards.
Something like this.
Something like this.
The cynic in me thinks it's cheaper for society to just let it happen instead of using tons of money on teaching citizens to get away from windows in the unlikely event of a meteor.
How many citizens do you think would get away from windows if they receive an SMS telling them to? And how many who weren't at the windows would go stand in the window to look at the great shiny thing?
Eventually when technologically we will be advanced this will/can be prevented.
Same with toilets, few hundred years ago we had none in apartments, now without one someone might die :D
I might be one of these people who would make whatever means to see meteor after warnings/announcements to go in underground bases(aka evangelion).
