In 1984, I sold the 1975 Cessna 172 I had operated for nine years and acquired a 1978 Mooney 201. I immediately put the airplane to work on a multi-stop trip around the country, quickly discovering how efficient it was. On the last leg of that trip, from St. Petersburg, Fla. (KSPG) to Mansfield, Mass. (1B9), I flew the 1029 nm nonstop in 6.7 hours using 52.4 gallons of fuel. That’s an average of 154 knots and 7.8 gallons per hour (or 19.6 nm per gallon).

As I recall (I wish my short-term memory was as good), I flew that trip IFR at 11,000 feet, even though the weather was good VMC, and my logbook says “slight tailwind.” I didn’t have any supplemental oxygen, and I don’t remember any adverse effects from that first-ever flight I made that was over six hours long.
