I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.
They’re everywhere all the time. Thousands of flights per day carrying millions of people.
I haven’t flown in several years, but in some years have taken 100+ flights.
For someone on the US coasts (especially North East) getting anywhere quickly beyond a couple hundred miles will possibly involve a plane.
