Perhaps not as high altitude as the stratosphere, but the US was experimenting with deployment and 'landing' of fixed wing aircraft from airships in the 1930s.

I will also +1 this as an i3wm user. I do use displayplacer and yabai together though. I have two identical external monitors that don't behave well with MacOS. Apparently the monitor's unique id's are not unique in MacOS. This causes MacOS to get them mixed up any time I disconnect from them. I have a keyboard shortcut that uses displayplacer to toggle between the two monitor valid configurations.
I lived in Austria for a couple of years in the late 2000s. They had an under 25 years of age ticket that was similar to this, but was very inexpensive. I think less than 50 Euros. It may have only been during the summer months though. Either way I traveled all over Austria and it cost me almost nothing. Wish I could be 25 again just for that.
