Wait...
I said the comment was in response to the idea that planes being used to crash into
things was unfathomable, not necessarily
buildings, per se...
If that's the source of confusion here.
Weak. Regardless, it's relatively irrelevant since hindsight's 20/20... if you or your grandfather really believed there was a clear and present danger to skyscrapers from suicidal airline hijackers, then you really sat on your hands this time. It's easy to be an armchair critic playing Monday morning quaterback.
Either you or your grandfather need to be less anal about human language... when people say "unfathomable" conversationally they do not usually mean "no one has ever thought or imagined it", it typically means "no one would expect it." Everyone in America lived with the expectation of NOT having our passenger jets crash into our skyscrapers. We clearly imagined the possibility (we have lights atop them), but people lived and worked in them nonetheless.
Basically, you grandpappy's remarks are a smartass crack that trivializes the tragedy. As if- if only someone had only remembered the Japanese kamakazi's in WW2 the WTC would not have fallen. You could live in paranoia and fear that every evil that has ever happened will happen again, but that's unrealistic, unexpected, and "unfathomable". People don't expect to get hit by cars, die of heart attacks, or become terrorist targets... if the victim says, "I never imagined a drunk driver in a SVU could plow through my living room." or "I was shocked..." We don't snidely say, "What? You've never heard of physics?"
You know, atomic bombs were dropped in WWII too... maybe we should living as if nuclear attack is imminent?
