Or on the civvy side; when a brand-new terminal was built somewhere in England about twenty years ago. Just before opening day, the users were shown around, so they could admire the wonder of engineering design.
"Where's the domestic terminal?"
"There isn't one; we don't have any domestic flights"
"Err; Aberdeen, Edinburgh, Glasgow, Newcastle" etc. A portacabin was hastily added.
"And this is the aircrew security screening section. All hi-tech and ready to go".
"Err: there isn't any access from it to the actual apron".
Gate installed in the fence the following day.
