The British Airways ad feels 'Titanic-esque". I guess that could be a variation on "post apocalyptic".

Yeah I kept today free expressly for the purpose of cleaning, and as of yet I haven't budged from the couch. I'm starting to think I should just give up and go do something entertaining.
Considering the disaster the opening of Terminal 5 the advert is prophetic. They were drowning in problems.
Yeah, the story didn't make the news much in the USA, but googling for this I saw that it really created systemic problems for air travel in the area and beyond.
The thing too about this commercial is, even apart from the drowning aspect... I dunno how bad Heathrow has been (been there a few times, none memorably) but the murky underwater view doesn't make it look much better or worse than most other modern airports I've been to.
