Swiss Helium

15.5.2015 · Category: Blog, Planespotting, Skywatching


We’re used to the occasional hot-air balloon flying over the city, but this is the first time we saw a helium gas balloon! The writing on it says Fribourg Freiburg Challenge which must have to do something with the website FRChallenge.ch, but I’m not sure what’s it all about or why this balloon was flying around here since my French is not good enough to understand the site.
