The only Commander I've owned is the 980. However, my dad owned an 840 (bought new), a 1000 (bought new), a Jet Commander (used, obviously) and my mom owned a Westwind II, a Falcon 10, and eventually a Falcon 50. One of my brothers owned an 840 and a Turbine Goose (as far as I know, he still owns the Goose, although I believe it's for sale), another brother owned a 500S, 690B, and then a Citation V.
I did own a C55 Baron for a while, a Great Lakes biplane, an Aerostar, and now a Citabria.
As for what I've flown... well, Commanders 500S, 690/690A/690B/840/980/1000/1000B. The only ones I haven't flown are the 900, and the pre-690 turboprops (680V, 680W, 681). The other turboprop I've flown significant time in is the Merlin IIIB.
As for jets, Citation 501/550, Jet Commander, Westwind I and II, Falcon 10, Falcon 50, Citation Sovereign (680), Learjet. Lots of time in Learjets. I was a 135 Check Airman in the Merlin IIIB, Falcon 10, Falcon 50, and Learjet at various times.
So that's my aviation resume!
