The mouseover text is trolling, since that would be impossible.

With a low enough vacuum in the surrounding area, a supersonic hand dryer should be able to apply drying without enough energy dissipation to damage the skin.

:Without reading your comment, I further changed the (as it was for me) "1940s" version of the statement to include the original "inadvertent" barrier-breaking (of prop-planes in almost always irrecoverable dives, without control surfaces that would work well in supersonic/transonic airflows) and included the developments made, which these days are somewhat more trivial than having to sit on a rocket that is released from a high-altitude bomber's wing, and fight to keep it flying straight and level. (We even had a supersonic airliner, for several decades!) There's a lot of interesting history to this, but not really the place to say it all.

Hand dryers were disabled in the early days of Covid in 2020 before hand transmission was ruled out as significant. I still feel awkward using one in a bathroom with others. I'm old and still mask when indoors publicly more than briefly. In 2023, I submit that you risk appearing hypocritical with a mask and a hand air dryer. Thus, I saw this XKCD as a reminder that hand air dryers had nothing to do with Covid. Still, there seems to be a bunch of fuss about the dryers. Apparently, some use mechanical air force (jet air) more than warm air for drying, from respectable gavi.org and wired.org in 2021 (https://www.gavi.org/vaccineswork/we-know-hand-dryers-can-circulate-germs-through-air-why-are-they-still-used and https://www.wired.com/story/wash-your-hands-but-beware-the-electric-hand-dryer/). I'm just rambling here; I'm not ready to do any editing.

: Ditto, the precaution of taping off every other seat (or two out of every three, etc), in order to prevent congregation of people in public seating areas. This forced every new arrival to always choose from the more limited number of pre-touched seats, rather than just advising people to randomly choose to sit only in any non-neighboured seats and so diluting the hypothetical risk. | : Ditto, the precaution of taping off every other seat (or two out of every three, etc), in order to prevent congregation of people in public seating areas.

: (I still mask up for entry to supermarkets/shops/indoor places of similar kinds. I would for buses/trains, if I used them. I'm otherwise still mostly "bubbling" with close family, or only going to places where we're mostly/all going, together or separate, but that probably equally applied before 'things changed' as well.)
