Surprisingly, we have business jets to thank for our wonderful network of FBOs in the United States. Many simply could not survive on the business generated by piston airplanes alone. Back when John and I were flying our Cessna 340 around the Midwest, teaching live two-day weekend ground schools, I remember sitting in airport cafes (also an endangered species) and watching Learjet after Learjet pull in for a quick turn on their way from coast to coast. The joke was that the early Lears gulped fuel at such a rate that the flight crew experienced a low-fuel emergency right after takeoff. When business jets became longer-ranged, and more of them could reach their cross-country destinations without a fuel stop en route, Middle America truly started to become “fly-over country.” FBO businesses there have become more precarious, and as a result, the number of our mom-and-pop FBOs in Middle America is declining.
