  • Paragliding is an unforgiving sport: you’re gliding, hoping to find updrafts to give you some more altitude so you can reach high enough to cross to another spot that hopefully also has an updraft, etc.

    At a guess, this guy was hoping that he’d find a last-resort updraft in this area. OP, do you live maybe in a small-ish built area surrounded by fields or forest? Those tend to get hotter than their surroundings and are great for updrafts. But generally you don’t want to land in residential areas, there full of obstacles which make for unpleasant landing conditions.


  • Oxygen is found in 3 forms: nascent (O), molecular (O2, the most common) and ozone (O3). Nascent oxygen, due to its electronic configuration (i.e how many electrons it has and how they’re spread out across its electronic shells) is unstable, and tends to quickly form bonds with another O, forming O2. This is also the case e.g. for hydrogen, which is usually found as H2.

    You can find O in this form in some environments, in the upper atmosphere there is enough UV radiation to break up O2 into O.
