This one is another one of AP's rather excellent panorama stitches which show a nice wide angle from the end of Nga Tsin Wai Road on the left to the buildings lining Sa Po Road on the right. The car park at the front of the terminal building can be seen in the bottom of the picture.
It seems that the only building that has survived the past 50+ years is the one on the far right (between the orange/red and blue signs). It's a nameless building that occupies 43 - 49 Sa Po Road. Everything else has been demolished and redeveloped. Here's an approximation of the same angle using Streetview.
Yep, lots of changes road-side as well. The flyover is the aforementioned single lane exit ramp from the airport carpark which pretty much blocks any kind of useful view. I have no idea if the flyovers will remains once the former airport area is finally redeveloped.
