Reus, 1969. The aerodrome between Reus and Constantí, a few kilometres from Tarragona, was a Spanish Air Force base. Today it is Reus Airport. In the tower that spring worked a duty sergeant controller, a relief controller, two Civil Aviation radio mechanics and two soldiers on military service. One of them, it seems, was Gabriel Font. He was 19. He collected flight plans and helped the sergeant.
