A friend and I owned N79PH from 1997 to 2009 and it remains a favorite airplane... 300 knot cruise, 35,000 foot ceiling and 1,800nm range. About once a year an airliner would pass by us, to see a propeller aircraft dragging a contrail and ask ATC, "What kind of plane it that?"
We made several improvements; the first Commander with (Meggitt) glass on both sides, the first RVSM Commander, and the first with heavy side windows and super soundproofing. The later added 70lbs of weight and changed the complexion of the plane... you could hear people talking in back, not wearing their headsets
The plane was originally a Parker Hannifin corporate machine, hence the tail number. One of their pilots landed on a snow covered airport between the runway and taxiway, taking out the right main gear. Apparently the left main gear collapsed in Bishop, CA a couple of years ago, someone is working to make it airworthy again. I hope so. I expect aging aircraft issues to increase the cost of operating these machines. We had a major pressure vessel service bulletin done by Eagle Creek during our ownership. The 1,000hp Garrett engine is a wonder to behold and a joy forever.
