The talk focuses on the early years of a new understanding of infrastructure, and uses various forms of representation (brochures, a feature film, architectural drawings) to explore the phenomenon in the case of the international airport just after the Second World War when infrastructural projects came into existence not only as “signs of themselves, but as trope, rhetoric, image, poetics.” London (Heathrow) airport became the main location for the film Out of the Clouds (1955), interpreted here as a training manual in how to learn the airport, namely how to negotiate infrastructure either/both because you don’t really know it is there or/and because you understand it as demonstratively sensitive to human craft and experience. The film’s treatment of infrastructure has continuing associations to contemporary conversations about forced labor, central state planning, territoriality, immigration, and citizenship
