In 1956, Silver City commenced London—Paris coach-air-coach/rail services via Lydd ("Ferryfield") and Le Touquet/Étaples. As Le Touquet Airport was not linked to the French railway network at the time, the journey between the airport and Paris involved an additional change between coach and train at Étaples. DC-3s initially operated these all-passenger services, which were marketed as "Silver Arrow" in the UK and as "Flèche d'argent" in France. "Silver Arrow"/"Flèche d'argent" was a joint operation between British Railways, Silver City and Société Nationale des Chemins de Fer français (SNCF).
