That's normal plume recirculation.
Nothing anomalous.

1. Welcome to the forum! You'll learn a ton...I have.
2. It's just you. IANARS (I Am Not A Rocket Scientist), but as the stack climbs into the thinner remnants of the atmosphere, this sort of recirculation is very common and apparently harmless. If I recall correctly, there are some spectacular examples of this from the Apollo days, with flame seeming to crawl 1/3 of the way up the stage.
3. Soak up the knowledgy goodness here for a while, then spring for L2. It really is "another level," and well worth the $$. Or ££ in your case.

I wouldn't say recirculation is "harmless"; I'd say rather it is "expected" and there is heat shielding in place to protect against it. But I haven't actually seen the math done: how much heating of the bottom of the rocket is possible with recirculated flow? Maybe although visibly spectacular the actual heat transfer is minimal and so it actually *is* "harmless"?

Since there was no "high-fiving", is it safe to speculate Mr.Steven dropped the flyball ala Kyle Schwarber?

There was clapping from the Hawthorne peanut gallery around the time the simulated booster landing would occur. Nothing to do with fairing recovery in all likelihood.

Elon confirms fairing recovery was unsuccessful.
https://twitter.com/elonmusk/status/979764513233715200GPS guided parafoil twisted, so fairing impacted water at high speed. Air wake from fairing messing w parafoil steering. Doing helo drop tests in next few weeks to solve.

Not close, but cigar for a good try

This is plain ridiculous...
Worse than that, it's one part of the Department of Commerce (NOAA) working at cross purposes with another part of the Department of Commerce (AST).
Edit: Oops. AST is Department of Transportation. Interesting that AST may be moving to Commerce soon...

I bet the test half is the one that landed safely on the previous attempt. Nice cheap test hardware.
These things are big $, so figuring it out sooner will save money sooner. Time to get on with it.

Do you have any source on this or is this just your speculation?
I doubt it is true.

I think they meant that SpaceX could use the one that soft-landed in the water for the air drop tests, not that they reflew it on this mission.

The rocketcam being prohibited as "earth observation" without a license is silly, but I think it's way more embarrassing that NOAA didn't even know about it when contacted...

It's not surprising a NOAA spokesperson wouldn't have a ready answer for that, NOAA has 12k employees and only a small number of them work on the remote sensing stuff.

Yes, it is understandable, but it's not a good look either. Just MO.

I would be more upset that they actually would be paying a warm body to rubber stamping obvious launch telemetry.
