So looking at differences between 39A and 40 and the one thing that stood out is the lightning rods. On 40 there were 4 around the pad, at 39A there's just the one on top of FSS. Guess being so close to the rocket it's fine?

There has been discussion that SpaceX has plans to build new lightening towers when they get an opportunity. Probably after the RSS comes down, the Crew Access Arm goes up, and after the tower is raised for the vertical integration hardware.

Before would make more sense. Removing the single mast atop the tower would disable the pad without new towers in place.

Why is SpaceX not running video until the last few minutes? It is their flight and rocket after all, not NASA's.

Their in-house webcasts usually start around T-20 minutes or so.

Looks like the SpaceX live streams only set to start at 10:01am eastern, but isn't that the lift-off time?

While the stream countdown is set for the T0 time, the stream begins earlier than that. So just use it as a countdown clock, that's what I do.

The Technical Webcast started at T-minus 30 minutes. Just funky music so far ...

What does it mean that there is an inconsistent date on the FTS for the second stage from the Range?

I'm (weirdly?) excited to see exhaust shooting out of that pad's ducts again.

Launch was scrubbed

They are saying TVC was reason for the abort. Interesting that they took it to 13 seconds on that decision.

Throwback preceded by a retraction of arms and a 1.5 degree back-off verification of the strongback per commentary.
