The Airport in Frankfurt is called Frankfurt Flughafen, or Frankfurt Airport (As it was renamed years ago)
The Airport company that operates and manages the Airport for the city of Frankfurt and State of Hessen is called Fraport
. Before that is was called "Flughafen AG", or just FAG.. yes yes go ahead and giggle (They even had "FAG" as part of the airport vechicles official license plates. AKA: FAG-001)
(Not Airport) shared the runway with the Civ. Airport for over 50 years and was a major US Airforce base up until its closing on 2005. Next time your go thru Frankfurt Airport, Look accross the Runways. Everything on the other side used to belong to the Ami's, but is now part of Frankfurt Airports Cargo City South.
