No matter how many different aircraft a plane spotter learns to spot, there remains one that you most enjoy pointing out to the airport crowd. That one is the trainer in which you logged your first hour, or soloed, or flew on checkride day. Maybe it was an orange-and-white Cessna 152, or a venerable PA-28-140 (the kind with the overhead crank for a trim wheel), a Cub, an Aeronca Champ, or something sleek and new. Doesn't matter—it's still the most special aircraft in the world. What's yours?
