I don't see why FSDT wouldn't make a professional Salt Lake City airport, even though someone else already is. There are plenty of Software Airport design companies that make the same airport. How many KMIA's, KLAX's and KJFK's are there you can choose that are from several different developers. I am waiting patiently for PACSIM's KSLC but would also like to see FSDT do their own version if they found an interest.
