Hong Kong International Airport is a marvel of engineering. It is among the most amazing man-made structures I've seen both in scale and in elegance. The whole airport is practically a small city in scale and I pretty much tired myself out exploring just the passenger accessible areas in Terminal 1 departure.
This, in my opinion is one of the most amazing commercial aircraft I've ever seen. I've watched a documentary of how they build these and it is an impressive logistical feat. Just as amazing is seeing something as humongous as this actually get off the ground.
I also got to do some people photography or two. This random traveler looked familiar to me.
Apart from this there are still the Arrival area and shops, Terminal 2 arrival and departure areas, and even the passage way that connects the two terminals running under the runways and taxi ways. Maybe I'd get to explore them some more someday.
This place even looks more amazing in Black & White. Until then, don't let the fear of getting lost deter you from going out to wander. More to come soon. :)
