Oh, I had forgotten "T9" -- that was such a ridiculous name. I would like to know the back story about how it was chosen.
(Okay, I just did a quick web search, and they're acting as though the T9 had never existed except for this old article, if you can read French:
A Roissy, l'aérogare minimale. Entre les terminaux géants 1 et 2, le T9 est un immense hangar destiné aux charters. Un peu déroutant pour les voyageurs qui s'y bousculent en été. – Libération (liberation.fr) )
