I've got a dollar some of you have been here a time or two. Anyway, got into Commanders when I was 5 years as I lived under an airway corridor between DET and PTK, more precisely Bloomfield Hills, MI. When we moved there in 1955 the traffic that overflew our residence was everything GA had at the time, C-310, TwinBo, Commander 560/680, and a Learstar or 2. The Cessna 310 straight tail was a favorite, but the majestic Twin Commander with their high-revving GO-480's had a distinct sound like no other, then a few Royal Gull's would come over and I thought they were Commanders until closer inspection-Commanders don't float, that squashed that idea. My first experience with a Commander was at Berz Airport where I got a ride in AC 520 N4186B and flew to Traverse City, MI. Got in the left seat and to taxi that beast was at least interesting.
Today I concur that the Twin Commander is the finest built twin available, both piston 500B, Shrike, 560F, 560 680, and on. For the turbine side of things, the 980 climbs like a homesick angel, and they are representative of a first class executive chariot.
