Maybe this is a stupid question, but after looking at the (incredible) photos, I couldn't help but think - how the heck did they go to the bathroom? Guessing it was a strictly number 1 24h. Even still...

I have friends who fly in paragliding competitions.

Look up "male external catheter".

Interesting. Do they also use condom catheter?

I used to fly gliders although I never did any long flights, but there used to be a tube that you would wear and urinate into and it would travel out the bottom of the glider.
