Yeah. John Essberger mentioned something about the LOX loading dragging the launch timing which caused the abort. It was right at the end of the broadcast.

It's really not, but then I was including in that all of the reschedules, and not just the last minute aborts. But I shouldn't call the reschedules aborts, so I kind of misspoke there.
Here is an analysis of the gains from densification pulled from a discussion about it:
The overall gain is apparently around 10%. The superchilled LOX is tricky to work with. The overall sentiment from the knowledgeable people at NASA Spaceflight Now forum is that this is early growing pains and that SpaceX will work at it until they get it right.
Even though there was a large window for launch in this situation, if there is any delay, they have to completely detank the fuel and perform a complete refuel of supercooled fuel. That would have taken longer than the time window allowed.
So be more ready for lots of scrubs until SpaceX gets the process down.
This is a particularly tricky one because there is such a slim margin for error. They need every drop of fuel and they had a little more leeway on the Orbcomm 2 launch than they have for this one. SpaceX is doing what they do, which is push the envelope as far as it can go.

Launch update from the SpaceX website today. A launch window has been announced for an attempt tomorrow (Sunday) evening. The weather looks to be excellent for either a Sunday or Monday launch.

Admittedly I haven't read through this entire thread, but is anyone down here in Orlando? Hubby and I just debarked from a cruise ship, and I fully admit to crossing fingers for launch delays while we were at sea. So I am uber excited that we may get a chance to see a launch tonight. Am thinking of trying the NASA causeway. Suggestions on how early to show up?
Good luck. Don't get too excited since SpaceX and SES are already saying the backup date is tomorrow. I hope the cruise was a lot of fun.

This super chilled lox stuff is getting annoying. Basically turns every launch into an instantaneous launch window.
And the longer this hold keeps up makes me wonder why they didn't launch Thursday as they are way over T-0 now.

A proper fueling. The range was fouled by a possible ship. The launch is not scrubbed yet. They are in a hold trying to confirm the ship or not.
Just loaded the webcast. I see the count is at T-1:33 but I have no sound and the video image is frozen. Has SpaceX stopped the video feed?
I went to the YouTube feed and that shows the count at T-10:42 and I can view the video feed. Still no confirmation if there really is a ship in the restricted zone or not.
