Airgliders

Airgliders stamps celebrate the ingenuity and skill behind unpowered flight, from early experimental gliders to modern sailplanes. Using rising air currents to stay aloft, these aircraft demonstrate the principles of lift and the close relationship between aviation and weather. Their long wings and streamlined shapes offer distinctive subjects for postage stamp design, while pioneering flights and soaring competitions add historical interest. This topical collecting theme connects aircraft engineering, aeronautical achievement, and the pursuit of flight without an engine.
