But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.

不過，這條法律從來都只針對狗隻。食環署向BBC中文確認，法律並無禁止狗以外的寵物進入餐館，「但食肆必須按牌照要求及食物衞生守則，確保食物安全和環境衞生」。至於餐廳內廚房等處理食物的地方，在法律上被稱為「食物室」的，則所有動物一概不准進入。
