Is there a fire at ATL 11/8/18?
 

Just pulled into the rental car facility and there was a huge cloud of smoke at the airport. Couldn't quite tell where.

Anyone know?

Could it be related to this? Link

I hate clickbait titles. It was the plane train, but the headline reads plane brakes.

I seriously doubt brakes, whether on the plane train or a real plane, would produce enough smoke to be visible from the rental car facility.

A couple of years ago I checked into the E skyclub and noticed a lot of black smoke around the south cargo ramp, the desk agent said they were doing "firefighting practice."

found it, September 2014:

I've seen the same thing a couple times in the past, most recently 2 months ago.

When doing live fire training at the fire training center, there will be a lot of black smoke.

Definitely looks to be comin from their fire training area. Next time you land on RWY 10/28 you can see the training area off the east end of the runway, behind the cargo ramps.

Looked exactly like this. This has gotta be it. When I got on the train from the Rental Car facility to the airport it was mostly dissipated and no planes had stopped landing or taking off.

I have seen the live fire training in ATL several times. Once the pilot announced that it was happening but still a little unnerving when landing.

Seen it dozens of times. Fun to be in SkyClubs when it happens.
