Something completely different: Flugservolator
    Yesterday evening I was briefly at the 
Oldtimer Fliegertreffen at Hahnweide. In addition to all kinds of old airplanes, they also had the 
Flugservolator.
This is basically a 
Silent Wings soaring simulator together with a bunch of mechanics to add movements and g forces to the flight experience. 
Of course, since it only does two axes and hence is limited in the amount of g's it can produce, it really makes the simulator experience quite a bit better. It is a lot of fun to fly an 
aileron roll and actually be turned on your head in the simulator :-)
The 
Flugservolator has been built by a number of students as part of their Technikerarbeit, supported by a number of companies.
If you want to use it for your event, you can contact them and rent the thing for a day. They also said that they'd built additional ones, if needed :-)
