A beautifully restored, bare-metal radial-engine trainer sits on the ramp, its polished aluminum skin catching the afternoon light. Aircraft like this served as the backbone of military pilot training programs for decades, teaching generations of aviators the fundamentals of formation flying, aerobatics, and gunnery before they moved on to frontline fighters and attack aircraft. Today, lovingly maintained examples continue to fly at air shows and museum events across the country. Project: 219309
