America's vintage power transmission infrastructure continues to cause hijinx as it slowly decays into spiderwebs and magic, but hey, THANK GOD FOR THOSE TAX CUTS!!

Total power failure at third world airport

I know you like to think this fits your narrative, but Georgia Power is a subsidiary of a large public utility holding company which is public. Taxes have little to do with this.
What I find more interesting is that they are claiming a fire in one part of their equipment spread to and damaged an adjacent facility which held the redundant power cables and switching equipment. So the airport had redundant power design, but still ended up going down because a central point of failure still existed.

Footnote: Totally talking out of my rear with no genuine knowledge, but I'm thinking that ATC probably had on-site standby power and that ATC was not compromised in any significant way...and I'd also speculate that our wonderful media does not care to make a headline out of that boring fact.Les règles de l'aviation de base découragent de longues périodes de dur tirer vers le haut.

Shouldn’t a airport that have big industrial backup generators for necessary parts of the airport if not all of the airport? As said above if they did they can’t have been compromised. The power failure had to of been internal, I heard that the air traffic control tower at the airport had power and was working as normal. Not sure if that’s true so don’t take my word for that unless anyone else can confirm it.~~CW2068~~

ATL had both primary and secondary power entering the airport through the same tunnel. That's not redundancy. It's like carrying the primary and secondary hydraulic feeds through the same parts of the aircraft structure. In contrast, London Heathrow has two separate power feeds from opposite sides of the airport and two independent power failure sensors on either side of the property. Sadly, this didn't stop BA from putting its primary and secondary data centers in the same building resulting in their major outage in May when a UPS was tampered with in an unauthorized way. Moral of the story: True redundancy always requires duplication. Not just components, pathways too.

I haven't invested a lot of thought in this yet, but a spokesperson commented that the actual 'thing' which burnt up was the switch that switched between primary and backup power.
I suppose you could have two switches, but then maybe you need a third switch to switch between which switch will switch between primary and backup?
Nice that Heathrow has two tunnels, but I would wonder if they do not meet somewhere at the same place where they are switched one direction or another...if so, "the redundancy" is a lot more like ATL than our magical dream airport with adequate backups.
...a lot of scientific engineering, indeed!
Conversely, I think with the $ and headaches involved there'd be a bit more investment in local standby generators (et. al) to keep from having to shut things down from the nuts and bolts aspects (repeating that this is not a safety discussion.) Our neighborhood was 'nuked' by a ice storm around 2006, and still has too many trees mingled with power lines...whenever we have a minor outage after a windstorm, you hear automatic generators kicking on all over the neighborhood...and then hospitals are pretty good about preventing power losses.Les règles de l'aviation de base découragent de longues périodes de dur tirer vers le haut.

More Flights Canceled in Wake of Power Outage at Atlanta’s Hartsfield-Jackson International Airport
Things were so bad at ATL that Chik-Fil-A had to open on a Sunday.
