Welcome.
This question is for everybody: do we have any credible, verifiable information that KK had a pilot's license?
I ask because I haven't kept up with all the threads and posts, either, so I may have missed something. I see a bunch of people speculating that KK flew herself to WP and back, but I don't know if there is anything upon which to base this speculation.
By the way, there aren't any general aviation airports in Teller County, and the nearest GA airports would be in Colorado Springs, Pueblo, Canõn City, or Buena Vista. It is possible that there are small landing strips on the South Park plains east of Wilkerson Pass, but it would be like landing a plane in the bush, and it would probably draw attention.
Speculation that PF being a farrier probably knows ranchers who have landing strips.....well, I haven't seen that up here. There are no "big ranches" like that, IMO. The only terrain that would allow it anywhere near Florissant is on, as I said, the flat land to the West, and that land is pretty useless for big ranching and has been broken up into relatively small parcels and was sold back in the 60's and 70's to people who wanted "land in Colorado." That's where the infamous Robert Dear had his compound.
Edited to add a link to a map of Colorado airports.
