My guess for #74 would be a DC-9 with Herman the Mallard on the tail, routed MKC-FSD-MSP-FAR-BIS-MOT.
While I was in New Orleans for Airliners International, a group of friends and I did a grim historic walk through the neighborhood east of the airport where the Pan Am 727 crashed in 1982. We used our smart phones to pull up a newspaper article that showed the houses damaged or destroyed by the crash, and aerial photos of the neighborhood taken a few days after the crash. There are two empty lots in the neighborhood, where people whose houses were destroyed chose not to rebuild, but otherwise all signs of the crash are gone. We also visited the crash memorial, which is behind a church south of the airport.
The people in the neighborhood did not question why we were there - I'm sure they saw a group of people walking around with their smartphones, and assumed we were playing "Pokemon Go".
