Here's a few things to consider before ripping into these guys.
1) What was their alternate? - Looks sort of like a turn at Twinz intersection. Maybe they had an alternate of GRB, MSN, LSE?
2) Runway change as they got close to the airport? We are still down one parallel runway in MSP. When they change the airport plan, things get backed up as you know.
3) Maybe the Center controller was "on the landline?" LOL
4) Maybe they fell asleep. I hope that is not the case. Because at this point it would be a hater field day on here. Especially since none of those haters has ever walked the dog during any of their long duty days.
Everything is conjecture until the facts come out. A look at the big picture, which the media hates to do, would be in order here before the Monday morning quarterbacking starts.
