A curious FrontBurnervian wants to know what’s up:
Black smoke in a big way? Looking South from terminal B??
Anyone know anything?
Update: A knowledgeable commenter says not to worry:
That is the DPS/fire fighter training area. It’s on the western side of the airport. It’s running about once a week or so, and it always freaks people out. But that is all it is.

Um, I hate to be picky, but I think the ‘time stamp’ time did not get the Daylight Savings treatment.
First responders at O’Hare in Chicago used to have a similar exercise, but they used an old airplane in a remote area of the airport to run the fire drill. The first time I came in over it, it was a real surprise to see a burning airplane surrounded by emergency vehicles. After that, it was fun to watch others’ reactions.
