I decided this afternoon (about 3:00) that I was going to make a run down to the other end of North Marginal and see if anything was happening at BKL... And as I approached "Hmm, that livery looks like Midwest...nah, probably a bizjet" but as I pulled up along side it was indeed a Midwest MD81 (according to FlightAware). Looks like it came in as MEP 8029 at 12:38 AM from MKE...
I don't see a departure scheduled for it on FlightAware.
As much as I would like to think that scheduled airline service was starting at an airport within walking distance of my appartment (especially with what I've heard about Midwest... I assume it's a charter for someone? Anyone have any more info about this?
