I don't think it's morbid at all to want to see these sites. Same as visiting a battlefield. You can pay your respects to the victims lost.
I too was going to mention the crash site at DTW
. I also think about it when I'm driving on 94 or Middlebelt. I was picking someone up 2 nights before that crash and a NW MD
-80 was landing at the same time we were driving out.
I pass the site of a Burlington Air Express DC8 crash often as it's across the street from my parents farm here at TOL
. I was living at home at the time of the crash and experienced it first hand. Four people lost their lives in that crash. Now the field continues to produce sweet corn and potatoes like nothing ever happened.
