@jeremyfaust There is plenty of transmission on planes. With masks, with immobile dummies, ignoring boarding, ignoring food and drinks, with wild type virus airline study estimated one infection from nearby index case per 55 flight hours. Reality has to be much worse.
@jeremyfaust飞机上有大量的信号传输。带着口罩，带着不动的假人，无视登机，无视食物和饮料，野生型病毒航空公司的研究估计每55个飞行小时就有一例来自附近指数病例的感染。现实必须更糟。
