This article addresses recent valorizations of infrastructure as a vital lens for understanding and explaining the constitution of modern life. It argues that greater care needs to be shown toward the evental (or events-led) underpinnings of infrastructure to accurately grasp the latter’s space-ordering powers. Indeed, existing work on infrastructure has tended to stress the postformative political effects of infrastructure, omitting the events-led triggers that continually reproduce technoscience realities. Even among scholars who recognize the role of social agencies in technoscience production, the propensity remains to treat these interactions as a bundle of rational negotiations and contestations that then go on to determine infrastructure’s final forms. To foster new appreciations of the deep dynamics responsible for infrastructure’s production, this article uses the case of an airspace upgrade in the South China Sea to demonstrate the centrality of events—including engineered ones—in steering technoscience development in air transport. It considers how a series of reframings, ruptures, and catastrophes—corresponding with commercial, affective, and accidental events—have precipitated fifteen years of modifications to airspace infrastructure in Southeast Asia. Analyzing two aviation report series alongside meeting proceedings, news articles, and semistructured interviews with a postqualitative touch, the article calls for renewed attention on the various exigencies that uncertainly drive infrastructural (and wider spatial) outcomes. The article concludes by reflecting on the theoretical purchase of evental infrastructure and the momentous geographies through which its politics must be tackled.

本文介绍了基础设施的最新价值，它是理解和解释现代生活构成的重要镜头。它认为，需要对基础设施的最终（或事件主导）基础给予更多的关注，以准确掌握基础设施的空间排序能力。确实，有关基础设施的现有工作已趋向于强调基础设施的后政治影响，而忽略了由事件主导的触发因素，这些触发因素不断再现技术科学的现实。即使在认识到社会机构在技术科学生产中的作用的学者中，仍然倾向于将这些互动视为一堆理性的谈判和竞争，然后继续确定基础设施的最终形式。为了使人们对构成基础设施生产的深层动力有新的认识，本文以南海空域升级为例，说明了事件（包括工程事件）在指导航空运输技术科学发展中的重要性。它考虑了与商业，情感和意外事件相对应的一系列重塑，破裂和灾难，如何促成了东南亚空域基础设施的十五年改造。通过分析两个航空报告系列以及会议程序，新闻文章和具有定性后感的半结构化访谈，文章呼吁人们重新关注不确定性驱动基础设施（以及更广泛的空间）成果的各种紧急情况。
