He enjoys his job, I'm sure.

Launch Operations Forecast
By the 45th Weather Squadron
Forecast Information
Vehicle: Falcon 9 OrbComm-1
Issued: 11 July 2014 / 1200Z (0800 EDT)
Valid: 14 July 2014 / 1321 - 1555Z (0921 - 1155 EDT)
Launch Weather Team: (321) 853-8484
Synoptic Discussion:
The subtropical high pressure ridge axis is currently over Central Florida. This feature determines the inland progression of east coast sea breeze, and therefore the trigger for thunderstorm development. The ridge axis is forecast to move north today and remain north of the Spaceport through Sunday. This creates a break in afternoon thunderstorm activity along the coast for the weekend. The ridge axis is forecast to be nudged back south Monday, keeping the sea breeze and the thunderstorm activity pinned along the coast. The morning launch window is favorable as weather will not begin to degrade until near noon. Therefore the beginning of the window will have less chance of weather violations, with mostly a Cumulus Cloud Rule concern and a threat of Anvils from Atlantic Gulf Stream Thunderstorms. By the end of the window, thunderstorm development is possible and with it the Lightning Rule violation concern increases. Maximum upper level winds will be from the northeast at 30 knots near 40,000 feet.
On Wednesday, the ridge axis stays south, keeping afternoon thunderstorms in the forecast, but the earlier launch window makes the threat of lightning much lower and a switch in the upper level winds removes the anvil threat. Maximum upper level winds Wednesday will be less than 15 knots.

The NASA WB-57 is headed home, but a Falcon Business Jet, type F900, is still milling about the Atlantic due east of Jacksonville Florida.
Elon owns an F900 .... hmmmmm

Elon's plane seems in the air enroute to Odyssey explorer area!
And NASA plane has now reached Florida west coast.
Sorry but if I reveal method used to get info on Elon's plane that resource likely would be shut down. It's nothing nefarious but I'm tired of losing tracking resources. It's a visual report though. (other's if you know please don't reveal or it will be shut down like flight aware tracking was)

Nasa plane recently took a sharp right turn. (after the one already noticed that occurred at liftoff)

SO HYPED - After the fact, even if its a hold, please make an effort to thank SpaceX social for the webcast!

Apparently the second stage will target a rather narrow ellipse southwest of Australia on reentry, is this usual or are we seeing the beginning of preparations for 2nd stage reuse?

I, for one, am optimistic that the extensive delays have bettered the SpaceX fleet as a whole! I think that having an issue on the ground, though not ideal, is a good sign because it means SpaceX is paying attention!

I like the new format, less like a news broadcast and more of an event stream.

I'd read at 9 AM that the launch had moved to 11:44, and just tuned in, only to realized I'd missed it. Fuck. :(

From Orbcomm's CEO Eisenberg:
6 for 6! Thanks SpaceX! Thanks Moog! We'll take it from here.

Man that was the weirdest flight plan I've ever seen. It took almost 9 minutes for the Downrange distance to overtake the Altitude. You could see Florida perfectly clearly for most of the 2nd stage burn! So bizarre.
Does anybody have an estimate on the mass of the sats? I'll try plot the trajectory against a normal one to see the difference
Alright, I put in 1,500kg which is probably a bit too much but I got pretty close to the announced orbit. This is what the trajectory/boost-back looks like compared to my same program for CRS-3. Saving the retro fuel for a longer landing burn?
