The COVID-19 pandemic [1–5] has caused the biggest crisis in the history of aviation, affecting operations [6–9], most notably airlines and air transport [10–17], including sectors such as industry [18–20], airports [21], and insurance [22], with some mitigation policies [23–26] providing some relief towards recovery [27–30]. Several years of continuous growth were turned into an almost total grounding in the short time span of a few months (Sect. 6.2). The official Chinese version of the origin of COVID-19 starts with the pangolin in remote forests as the carrier with transmission through bats to people (Sect. 6.2.1) who eat them; the Western press has reported a rather different story (Sect. 6.2.22) of origin in a laboratory working on biological weapons of mass destruction near Wuhan, where the outbreak started. Several analogies have been made with the COVID-19 pandemic (Sect. 6.3), including (Sect. 6.3.1) earlier historic pandemics with much higher death rates; (Sect. 6.3.2) world wars, which caused a much larger number of deaths with attempts to occupy territory; (Sect. 6.3.3) natural disasters, like earthquakes, volcanic eruptions, floods, fires, and tsunamis of much more limited geographical or temporal extent; and (Sect. 6.3.4) biological weapons of mass destruction with no known cure, leading to diseases whose spread is extremely difficult to contain.
