The development of practical aerostatic or lighter than air balloon flight in 1783 marked the emergence of a new way of being and becoming mobile, one that also involved an important technical and experiential transformation in earth-atmosphere relations. This paper narrates an account of the distinctive kinds of spaces of which aerostatic flight is generative. At the centre of this account is the claim that the affective materiality of aerostatic flight is simultaneously processual and possessing of what political theorist Jane Bennett calls 'thing-power'. In developing this claim, the paper draws from a range of historical and contemporary accounts of aerostatic flight in order to elaborate upon three aspects of the spaces of things becoming aerostatic: the distinctive kinds of sensing of which aerostatic flight is generative; the differential qualities of affectivity in which the movement and materiality of aerostatic things participates; and the kinds of vertiginous events in which the felt movement -actual or anticipated -of aerostatic things is implicated. The paper concludes by speculating upon how attending to the distinctive and sometimes disquieting materiality of aerostatic things might contribute to geographical engagements with the spaces of air and atmosphere.

PreambleIt begins rather suddenly, torque-like: a sense of anchorage giving way to tensile instability. It happens as a minor corporeal reorientation, an incremental rebalancing of body-space, an unthinking adjustment of feet: the sensing of a kind of torsional ungrounding. This sense is quickly replaced however by something else: steady uplift, generated by 5500 metres cubed of enveloped helium, the force of which is balanced by the steel cable unwinding, slowly, from a point hidden somewhere below the ground. And so commences the experience of ascent, one which, save for wind, metalcreak and audible cablestrain, is largely silent.Derek P McCormack Trans Inst Br Geogr NS 34 25-41 2009
