I just discovered an odd sight at LSZH. At Gate E23 there are two objects hanging in the air - one is a guidance system for docking (can't remember the right terminology) and the other seems to be a bit of a gate. I am attaching three screen shots - one shows the floating objects, the second is an overhead showing the gate location and the third will help you locate the site in the airport.
I know the Swiss are clever people but I don't think they have discovered the secret of levitation! Or maybe they have?
