Can we get a picture of the sonic boom mist cone. (That scared me $hitless)

Scared me as well. The condensation cloud happened just as the vehicle went supersonic, and I had an instant flashback to CRS-7 for a few moments.
Maybe it was ice cloud (Cirrus) and both position of sun and ice crystals made it so bright as sonic boom hit it?

Quick checking of basic of meteorology tells me that only cirrus clouds (plus massive thunderstorm tops) exits that altitude.

Was that audio of the sonic boom? I could have sworn I heard something at that exact moment.
Yes, some tell stories how they can hear Aurora Borealis and this was ten times lower, and sonic...
(It was SpaceXer puffing into the mic before saying the line in the loop...)

100 consecutive launch successes for Falcon 9!

Since CRS-7? Or since the AMOS-6 pad RUD?

CRS-7 was F9 flight 19. This was 119. Amos 6 isn't part of the count, and was between 28 and 29. The in flight abort test is part of the count.

Liftoff for the 100th consecutive successful #Falcon9 mission!

This #Starlink mission will complete the 1st orbital "shell" of the internet satellites, and allow SpaceX to offer the service to non-beta users.

To clarify, this batch still has a few months of checkouts and maneuvering into their final orbits before the service can be made available to the general public.

A small movie clip of today’s Starlink launch. I love how fast it climbs.

Here is a comparison between the Starlink L27 and L28 telemetry.

Some points of interest are:

1. The younger L28 booster B1063.2 took a more conservative path through MaxQ, possibly to the advantage of the now 5 times re-used payload fairing half.
2. L28 ran a little harder later in the boost phase, perhaps with the confidence of youth.
3. The L28 S1 telemetry drop-outs on entry had no impact on the success of the landing, as you would expect from an autonomous flight controller.
4. The S2 profiles were practically identical.
5. How it looked from my place.

GO Searcher and GO Navigator are due to arrive at Port Canaveral on Friday evening.

Each ship should hopefully have a fairing half from the latest Starlink launch.

Here's the archived link to the SpaceX web page and my poor attempt at converting it to a pdf file.

It's a busy evening in Port Canaveral as GO Navigator rolls in with one fairing half followed by OCISLY with a party going on deck. GO Searcher is expected later this evening. OCISLY has been completing inspections/sea trials

At least one half looks good.

First fairing half has arrived in great shape. GO Searcher and the other half are due in around 90 minutes time.

SpaceX workers have sent two collection trucks to Port Canaveral so safe to assume both halves are good.
