Emirates Airline’s shower-spa. Imagine that at eight miles high.
“We understand that air travel can be tiring, especially during long flights. That’s why we included two onboard Shower Spas as part of the First Class experience on the Emirates A380. From the state-of-the-art shower system to the classic walnut and marble design to fine linens, the Shower Spas were conceived with your pleasure and convenience in mind.”
A far cry from the usual cattle-car experience. The 21st century is redeeming itself.

I guess they don’t use crude oil in that spa…
Heh. I hope not.
