Well im not sure on Superman but St. george was definetly an eye opener for me. When i fly my Roo at my local field im the only turbine flyer so usualy everyone lands when i start up.

But playing doge-em with 5 other jets was wild. Preaty fun. I can see why you need a caller to stand behind you to call the traffic. Superman must have even more planes up at once. WOW.
take care
