I've been in and out of Jackson numerous times, both VFR and IFR. With reasonable planning and a reasonably performing and lightly loaded airplane flown properly, it's a really great place, in and out. Poor planning, a marginal but heavily loaded airplane, and improper flying has caused the vast majority of accidents in the area. Several years ago, the USAF lost a C130 which hit the rocks in IMC; the entire family which owned a construction company in Cheyenne died in a 310 some years before that in IMC; there have been many, many other fatal accidents of varying kinds, both in VMC and IMC, but all of them had one of those 3 issues, poor planning, poorly performing airplane, or poor flying. This Mooney incident appears to have had all 3.
