Infra_MANC exhibition that I co-curated last spring.
If you're interested you can browse through the slides on 'Vertical Urbanism and the Forgotten Plans for Heliports'. The image above is an example of the kinds of unrealised plans for rooftop heliports that I am examining. This particular drawing, from the early 1950s, was for a helicopter station in the centre of Liverpool but was not actually built. (Image courtesy of Liverpool City Archives.)
Infrastructure and the Rebuilt Post-war City, where I will drop the Liverpool-specific examples and add in a little bit more on London and Birmingham. I plan to write this material up as a full paper in the next few months, but in the meantime you might want to read the 'helicopter dreaming' chapter in the print catalogue from our Infra_MANC exhibition - copies still available for just £10.
