Love the confusion over this in the Bahamas:

I love it! Jill's all like "It's a rocket, you idiots."

"It's ice spray coming off the back."

I guess that settles our discussion about LOX ice.

What's fascinating about this video is that you can see the core's wake as it passes through the upper stage's plume. I've never seen footage like that before; I've no doubt that rocketry professionals will be dissecting images like that with great interest.

English accents!

At least they didn't say UFO

Could that be the fairing coming off at about 0:57 (rather than ice?)?

That video makes me think Abaco Island would be a great place to watch the first Falcon 9 RTLS mission from.

I do believe that is fairing separation and not "ice".

Spectacular lighting conditions, vehicle in sunlight while flying through dark skies makes for some excellent photography, too bad most autofocus cameras have trouble with it.

Correct. Both halves of the fairing are visible.

That was an awesome video! Great find...hopefully someone will forward it to Musk.

This is my favorite video so far of the Falcon 9 SES 8 launch. The reason it is so interesting is listed in the video description. This crowd knew exactly what it was seeing, and the emotions are - well, turn up the sound and you'll hear what I mean.

I missed not seeing Molly during the launch webcast! Where’d she go?

SaxtonHale · « **Reply #769 on:** 12/04/2013 10:07 pm »

I thought I heard her on the net during launch
(Only because I was just re-watching the launch, not that I keep track of her..)

Thinking back, you are very well right. Would have been nice to see her reaction on the successful day... Maybe we’ll see her again on the upcoming launch!

They didn't show either her or Insprucker on video at all (though we did of course get Insprucker's voice), so I think maybe they were a bit sick of the constant scrubs and decided to just go with "OKAY WE ARE LAUNCHING IT HERE'S THE LAUNCHPAD" rather than do the whole media schtick like the first two attempts & previous launches - hence the livestream also starting ten minutes later than before and going straight to the terminal count. Would make sense, no?

Here is a suprisingly good quality cellphone(?) video from Cocoa Beach - my guess - with some interesting commentary.

"That doesn't look right", "It's going down"

To be fair, I guess they haven't seen many launches just after sunset, illuminating the upper stage plume so well. (Even the stage 1 RCS was barely visible) Or is it RP-1 plume that makes it so visible?

Gorgeous image.
That shows that the stuff coming out of the disconnecting umbilical is NOT on fire. At least up to the moment of this image. Looks to me like residual LOX boiling off.

That Bahama video is funny listening to them try to figure out what it is. First meteor ever to go up instead of down!

But by that time the rocket is going mostly horizontal... so they can't really really tell that it isn't descending. The expanding plume cloud of the MVac also probably makes it look like it is getting lower, not higher.

Still impossible to mistake for a meteor, if the viewer had ever seen one. Meteors only last for seconds, if even that.

OH I don't know about that! I saw a fireball track north of me, moving low on the horizon, west to east through at least 60 degrees from where I watched. It moved seemingly horizontally, then terminated in an explosion. It took several seconds, at least 10 seconds it seemed to move through the angle. So it all depends on the meteor.

This was in maybe 2010. Turns out the fireball exploded over Wisconsin and they found pieces. I was watching from Cedar Rapids, Iowa. I never bothered to find the ground track but it may be recorded somewhere.

10 seconds is a few seconds. Also 60 degrees in those 10 seconds.

Or 30 seconds.... Fortunately these don't seem to be that frequent. Longest I've seen were in the 3 second range. I remember seeing footage of one when I was a teen that skipped across the Midwest sky for quite some time.

Here is another video, with some more knowledgeable adult (& kid) commentary: (the quality is so-so, but you can clearly see the 1st stage as a separate dot, and the fairing halves become visible halfway through the video)
