Elon does it again. A genuine, real-life Iron Man!

Well done and an amazing achievement. Between SolarCity, Tesla, and SpaceX I am constantly impressed by what Musk's companies are doing.
I hope the US keeps tax incentives around for solar panels and EV's. There is so much progress being made it seems crazy to pull the plug on supporting those efforts now.

Impressive! The guys at SpaceX are real heroes! Let's hope they will get us to Mars and beyond!

Well, this is good news all around, not only has it been proven, but the rocket can be taken apart for study, and possible revamp.

All I really notice is fuel being wasted. A rocket at low speed looks sillier than Monty Python. We don't need ICBM launch times for space work, we need wings in use as far up as they are useful.

The world got to witness a sea change in outer space launches. With reusability, suddenly the expense of a launch gets so low that a whole new world of options becomes available for manned spaceflight. e.g., the problem with shielding astronauts on long space flights was a problem because the protection was highly correlated with weight. Now heavy shielding is seriously less expensive to loft. Another example is that the extremely expensive sea recoveries will soon be history as well.
A solid vision and an innovative spirit can work wonders. Go SpaceX!
BTW, Jeff Bezos: You are not a member of "the club." The X-15 is and the Space Shuttle is, but Blue Origin is not. The Falcon is doing real work for real money and making a profit. BO is creating an extremely dangerous toy for rich kids --- and you and Virgin Galactic are in that "club" ---- one with a very low bar. In fact the bar is almost exactly 1/900th the height of the Falcon 9.

Bob, the fuel is an insignificant expense. That 15 story 1st stage rocket and the 9 engines on it is extremely expensive, so being able to save and reuse it will save SpaceX a lot of money and enable them to reduce the cost to orbit for all of their clients, including NASA. You seem to be suggesting that we use airplane technology to get cargo high up before using something else to get to orbit. That would use a lot more fuel than a rocket, be more expensive to build and be very time consuming to launch. This think took less than 10 minutes to deliver a payload to orbit and come back down for a landing. That is amazing!

Are you kidding me is all I could think. Wow! Seeing this, and seeing it executed so well is simply stunning. Cannot even imagine the maths that goes into something like this.
Awesome accomplishment guys, simply awesome!

This is the real beginning of commercial space!

Yankee ingenuity at its finest. The current government leader gets rid of the Shuttles to make us dependent on other nations for our space activities and kill our lead in space exploration. So the private sector takes over and hits a home run. Get rid of the red tape, bureaucrats, and self-minded politicians and look what is accomplished. Let's take a lesson from this shall we?
