5 Euro Nieuport

This coin belongs to Spain's "Aviation Pioneers" series, issued to mark early developments in powered flight. The Nieuport connection runs through Spanish military aviation history — Nieuport biplanes were among the first aircraft acquired by the Spanish Army's nascent air arm in the 1910s, with several operated from the Cuatro Vientos aerodrome outside Madrid. Spain's early military aviators trained on French-designed machines almost exclusively, and the Nieuport types saw service in the Moroccan campaigns of the Rif War.
