Summary

Hailing from a time when all trainer aircraft were armed with a tailwheel, the Cessna 120 and 140 would morph into the most popular training aircraft of all time: the tricycle geared Cessna 150. Notoriously underpowered, the fabric-wing economy model 120 (no flaps) and full-featured model 140 (flaps), and later the 140A (modern style metal wing) would usher thousands of pilots through initial training and into larger aircraft. But for the purist, these 2-seaters are lightweight joys to fly. With a little practice a lot of respect for their limitations, they can take you most anywhere in the backcountry.
