From what I read about it. I would not say it has anything to do with bush pilots. This appears to be a program that reads NASA data about active Forest Fires and than gives you the opportunity to go there. From what I read it uses a Effect file too create the fire at the location giving Almost the same way Vapor trails work so there is no actual scenery changes made it just uses an effect file to create the illusion of fire.
I can not say if this is a decent program or not but I am not sure of how good it really could be. I guess it depends on the effect file that is used and if there is more than 1 file for different fire sizes.
Sounds a little skeptical to me. But who knows it might be okay.
It might be the same way that Active sky creates a hurricane that you can see and fly through . This is pretty awesome Since I was actually a crew member of Weather Reconnaissance Squadron Four VW4 known as the Hurricane hunters and have actually flown through a real hurricane It is not that far off from the real thing.
