Looking at Flight Radar, at least pre covid, was absolutely astounding every time. The scale of humanity is really incredible to me. There are more people in the air than live in my city. When I first flew to a big city, Osaka, I flew over 3000km of desert before even getting out of my country, and then bam, everything was absolutely infested with life and activity. More 'stuff' than I had ever seen. Looking at Flight radar not long ago, I saw the veritable stream of Japan Post cargo planes one after the other flying into HK or China, I forget. I remember thinking that just the postage was more planes than were aloft where I live for all commercial, travel and personal activity combined.
