I have 'jumpseated' with a Virgin Atlantic captain who has participated in an ITVV video.
The videos are very detailed and informative, but I have been told that the editing can be rather dire!
You could have been watching the video where the flight should be in its descent phase, but the actual screened picture shows a clip of the a/c in its climb/cruise phase.
I may be wrong, but it has certainly happened before......
