Hong Kong (series) - Rod Taylor (1960) - Kai Tak Airport, Kowloon

The final shot from the series pilot is when Evans' female colleague is shown off at the airport. This image below shows the not-so-clear RAF Officer's Mess on the hill in the background which puts the plane in the RAF section of the airport.

Actually, by 1960 when this series was filmed, the new runway had already opened so this looks to me as though it was most likely stock footage. This isn't surprising given that this was the pilot episode intended only as a showcase for the show in the hope that it would be commissioned. This also explains why much of the on-character shots are either on a studio set or use back projection (in one scene, Taylor is filmed against a back projection that has been reversed - showing the Chinese characters written backwards).

Luckily for us, the series proper does use proper location filming and we'll get to some of those over the next few episodes.
