I asked this question over on Travel.se asking why a plane could only be moved by its pilot, and received a comment saying it would probably be a better fit for this site. Would it be a better fit here, or is Travel.se appropriate for it? If you guys want it, I can flag it for migration to here.
Since it does not seem to be about the "passenger side", I would expect it to be fine here, particularly if you focus on the regulation side (i.e. "is there a regulation that mandates so-and-so?"). But wait to see if it gets closed on Travel first, or ask the mods there (maybe in chat) if they feel it needs to be migrated.
