To me, the original question is a bit odd to be blunt.
Are you after odd questions or daft questions? It sounds to me like maybe you're actually after questions about things that may seem daft.
If that's what the list is then it becomes interesting, otherwise I think it's just a bit of an odd list.
You don't really depart from a Terminal when you fly. You depart from the departure lounge.
The building is labelled as a Terminal, but that doesn't seem all that daft to me either. What would Bridgenut and the rest of you have the new edifice at Heathrow called? "Departure Built 5"? Then there would have been a comment on here damning the PC brigade (I know it would have nothing to do with political correctness, but I'm not sure that would necessarily have stopped people from saying it).
