The question I have is that at one point in the movie, the nose-gear is extended, but the mains are not. It only occurs for a few seconds at around 2:20, but there is another video "Belly of the Beast" that is just an extended version of the first video with an even more obnoxious song that shows it going on for quite a while, seemingly tens of minutes.
Can the 747 extend just the nose-gear? My understanding was that it could not, and I cannot think of a good reason to be able to do that. I thought that the large handle to the right of the center console was the control for the gear.
