It's happening once a year. A Mega FlyIn at continental europe's biggest airport. This year the date is November 11th between 17UTC and 22UTC. To make it a little bit more difficult for the controllers we picked four airports so that traffic will reach Frankfurt from four different directions. Those airports are Brussels, Schiphol, Vienna and Zurich. At those airports you can expect full ATC. However, aircrafts from other airports are also appreciated!
