I believe at least one of them slid off a taxiway. Then again, the company will sweep it under the rug and we will never learn about or hear about it.

No excuses for going off a taxiway, however I know at minimum that Alpena is a ******* hole. Heck, the FAA stepped in and had to make sure the station was properly trained on de-icing procedures... Since no one was.

Even the bigger airports try to get away with crap: Madison Wisconsin said the the middle 50 ft of the runway had been cleaned but the fact that the brakes were mashed to full and the aircraft began weather-vaning when the TRs deployed says otherwise.
