Not sure why Americans think that’s fast. My record speed is 640. 100 is less than 2 miles a minute. Yawn....
The stares I receive from my wife have been known to travel at Mach 1.
From your screen name, I’m assuming in the air?
Prerry good Trans-sonic. is that your speed over land with a good tailwind at high altitude? Or was that KIAS? 😉
I’ve broken 750 mph (over the ground) in a 767, but we were at 39,000 feet with a ~200 mph tailwind. (NY to UK).
