I finally shelled out the $ for the paid version of a flight radar app because I was curious. The friendly skies are mostly empty. 85ish% of all flights in and out of Bay Area is from/to China.

I always had the free version but the paid version will ping me every time a flight goes over me(my phone actually) and for a mere $6.99/month, I can find out the air traffic of the area. It’s an affordable hobby for covid. I highly recommend it.

I don’t know what it really means but just an observation.
