Falcon 9 v1.1 Maiden Launch!

Wanted to watch this live to get booster info but was someplace with no reception. 
Vid here:

Also this article is pretty cool. Here's the bit about the attempt at recovering the first stage:
Once it was back in the atmosphere, it lit its central engine to slow itself further. That's where things went wrong, though, as the booster started spinning. According to Musk, this "centrifuged the propellant"—spun it to the tank's walls and kept it from feeding into the engine. As a result, it hit the water hard, leaving the company's employees with pieces to recover. (This rocket didn't have landing gear anyway, and Musk said that the added hardware would act like fins to stabilize the spin.)
With the information they gained from this flight, however, Musk said that SpaceX has "all the pieces to do full recovery of the boost phase," which he expects to be attempted early next year. In the intervening time, the company plans to gather data on re-entry during two more flights.
Recovery won't be cheap. In response to a question, Musk estimated that saving the fuel to perform a controlled landing on water requires sacrificing 15 percent of the potential payload; returning to land will take a 30 percent cut. But Musk said the boost stage is about three-quarters of the total cost of the rocket, so being able to reuse it would provide a substantial net gain.
Beyond these findings, not everything was rosy about today's launch. SpaceX also tried to restart its second stage engine (which is necessary on some flight trajectories but not for today's launch). The engine "encountered a condition it didn't like during repressurization," though, and the process was shut down. Musk said that the company has a good idea of what went wrong, and will address it before the next flight.
