I was driving though Troy around 3:30ish this afternoon and off to the northeast I see a Northwest 727 fairly low. I see planes inbound to DTW all the time and this plane was going northwest over the north part of Troy towards Oakland Pontiac I believe. Nowhere the direction they fly to DTW. I checked for a Northwest flight from Boston since the Pistons are playing Boston tonight, but i didn't come up with any matches. Could this have been a Chrysler chartered plane?
I wish I would have had the time to drive up to PTK and check it out.
