Nice shot of Chicago. You got my house in there somewhere, slightly left of Sears Tower (black tower on left w two white antennae) and a bit further out.
I think it was the Viet Nam war that caused air travel to become routine and boring for most Americans. Before that conflict, large movements went by troop transport at sea. But during my service period (1964-'67) I was jetted across the Pacific numerous times, became accustomed to it, and continued jet travel when I returned to civilian life.
Spending a couple days on the train going from California to Pennsylvania, as I did all through college, was suddenly unacceptably slow. However in recent years, tonyf has caused me to reconsider. Going by jet may be faster, but by train I'd reduce my carbon footprint
by 90% !! Quite amazing.
