Concorde Airways is an airline in Flight of the Living Dead:Outbreak on a Plane. It does not fly Concordes, it is simply a name. The film's plot is that Flight 239 in 2007, full of eager Tourists, flying from LA to Paris, is overrun by Zombies, and as usuall, they must be blown out of the plane to save it. It is most likely a French airline because the Concorde was largely a French Development.
