Obviously the fans would blow in from the sides, but you could get the racers going hundreds of miles per hour.

The single most dangerous race a human could engage in.

Advanced level: 2 laps - racers need to fly THROUGH the big fan.

I love this idea!
The fact that I posted it almost 20 years ago is completely irrelevant to how much I like the idea of indoor flying Superman Roller Derby. [link] The math buffs on site at the time estimated speeds of up to 90 miles per hour.

Hmm. I was thinking of horizontal blowers getting the flyers up to 400, 500 mph but yea, you thought of the general idea first.

Let me see if I can add a further innovation to salvage this from being too baked. My guys wear hats or something.
