Thanks for posting that, Bruce. It makes you realise just how busy major airports are.
It's unfortunate that he didn't state the locations of the images, although perhaps I just couldn't find them.
Heathrow was recognisable and some could at least be narrowed down to country or airport judging by the preponderance of a particular airline, eg KLM at Schiphol.
ETA Topical note.
A decision on which London airport is to be expanded is expected to be announced about midday today. It seems likely that Heathrow will be the lucky winner.
