From what I recall, there were thunderstorms nearby that night. I was living in Livonia at the time and I remember storms. The paper published the cockpit transcript leading up to the crash and I recall the pilots talking about the clouds being black as hell and also them talking about Pan Am 747s.
The crash site memorial is on a hill, on the east side of Middle Belt Road and between the east bound lanes of I-94 and the on ramp for I-94. You will see it if you drive by the site around August 17 because the hill will be covered with flowers and wreaths etc.
I remember the aircraft taking down the traffic lights at the exit for Middle Belt and I-94 as well as Middle Belt and Wick Road. They were replaced soon after as they were still cleaning the site.
I believe I-94 was two lanes in both directions before the crash. They rebuilt the I-94 bridges soon after and then widened I-94 too. I am surprised too that the Norfolk and Western Railroad bridge didnt get damaged or need to be replaced out of fear that it was weakened.
I had a relative that was driving west on I-94 when the plane crashed. He saw the explosion in his rear view mirror.
Another guy I used to know worked at the weather bureau at DTW
(located at the Signature Flight Support building) He was coming in for his shift at work tonight and had just passed Wick Road when he witnessed the crash. Had he still been stopped at the light, he could have been another fatality.
