Oh sure. Coming the other direction the planes were both closer to 500 mph... but airspeed was probably similar both directions?

Yep. Mach refers to speed in the medium. It's where the compressibility boundary is. Part of the reason it's hard to go that fast is that it gets bumpy right at the limit of compressibility.
Not to burst any bubbles (or create any pressure waves), but Mach one is air speed, that 674 was probably ground speed while he was caught up in the jet stream, so still only Mach ~.8 Mach.

Yeah in The Right Stuff, Tom Wolfe spent quite a bit of ink on explaining the problem and I don't know if I ever really got a handle on it.
It was interesting that on the way over, CFW was at Mach 1. I didn't think they did that ever, even over the ocean...
Speed
673 mph (Planned: 557 mph)
Altitude
33,000 ft (Planned: 33,000 ft) <ââ- Flightaware info
At 33,000 feet, the speed of sound is approximately 674 mph. <â- I googled that part

Is he scouting new territory? The math on those long hauls is interesting - something between arc of intercept and aiming for where your target will be, all in 3 dimensions plus weather.

AFW & CFW are both in the air, separate airplanes, on their way home and *knock on wood* the weather is bright and clear so no delays?
CFW is currently 500 miles north of the planned route, LHR to DFW, flying over the lower third of Greenland where the planned route was to just skirt the lower end of the island. 4000 ft higher than planned and 50mph faster than planned, but still projected to arrive on time. Hmm that's some higher math I will never be able to conceptualize.

Sheâs actually done some good stuff in her genre(s). Now, I think, sheâs got so many people (agents, touring people, assistants, etc) reliant on her to churn out product that sheâs becoming a dancing monkey. But thereâs a reason she got popular.
If anything, really, that song title would fit much better in every political thread on here.
