On September 17th, there will be sort of an "open doors day" at MUC. Many vehicles which are normally only used on the apron will be displayed at the MAC - Munich Airport Center. The admission is free. Partly, there will be free parking. Bus tours around the airport (which I really recommend) are offered at a reduced price.
