At the risk of being overly pedantic the cabin shots in the Swissair CV990 video are clearly of an early model DC8 (pre -60 series). The seats and window curtains are a clear give away. The exterior views and cockpit shots are however of a CV990. I witnessed a Swissair CV990 go around on rwy 13 very early in my HKG career. Presumably a bit fast and high over Kowloon City just as I was leaving Kai Tak and a nice pull up with large wing tip vortices following the aircraft over HK Island on a lovely sunny afternoon. Someone who had flown both the CV880 and 990 once told me the 990 was quite difficult to land compared to the 880.
