Freighter/747 Crew Base in Vienna/Austria??
 

A friend of mine contacted me, he was asked by an austria based pilot that supposedly there will be a crew base for a chinese freighter company maybe flying 747s, but that is not the point. He thinks it Shanghai Airlines but could not find out more details.
Does anyone of you know if there is a crew base for any crews regardless of company that will be basing crews there?
Would be nice to know. Many thanks for your inputs,
