arena idea been brought up?
I was wondering if anyone had brought up the concept of putting one of the freefall turbines into a larger building, widening the opening to slow the air speed, and then trying a wingsuit game inside. It'd have to be a minimum of 50 ft across so you'd need to run the turbine at full speed the whole time(or build a whole new system) and the design on the air flow would be a B!+€#. But it could be Awesome to watch a game played In flight...
