%A T. Kolsteren %T Planning for new (Air)planes: Using a multiplanar approach to assess uncertainties in regional airports of the Netherlands %X Deregulation, privatization and globalization have rendered the aviation industry increasingly dynamic, which causes regional airports to grow suddenly and drastically . A major consequence of these changes is that it creates uncertainty. I examine how neoliberal and communicative shifts in governance have changed the nature of uncertainty to what are called ‘intersubjective uncertainties’. In order to asses these uncertainties i use Jean Hillier’s ‘Multiplanar theory of spatial planning and governance’ to do a comparative case study analysis of Lelystad and Eindhoven airport. A consultative body called the ‘Alderstable’ is instated in both airports thus interviews with its participants is the main focus of gathering data. As this study will show, intersubjective uncertainties play a major role in the expansion of these airports mostly related to issues of morality and information. I recommend planners and policy makers to stop working towards a fixed end-goal and redefine planning to an ‘empty signifier’. %D 2017 %L theses_frw525
