The twilight of Sabena's passenger helicopter operations. The airline had sold its S-58s but acquired two others from Chicago Helicopter Airways to carry out the remaining services. N869 and N878 became OO-SHP and OO-SHQ, respectively, but flights ceased on 1 November 1966. The Brussels heliport closed immediately. Photo by: Eszter Pozsgay / Fortepan

Brussels at war? No, this is the festive opening of Sabena's helicopter service to Paris - Issy, with the whole new S-58s fleet making the trip. In 1963, amazingly, a Breguet 941 STOL transport was allowed to land at this city heliport. Photo from: Nationaal Archief (Netherlands)
