Attachment 237859
So close. The stage separation might have been the coolest part of the launch vid (18:36 because linking a youtube vid sucks): |
Better landing vid just posted.
Poor RCS system is working as hard as it can to keep it upright. |
Why don't they just put some self inflating floaties on it and let it land in the water?

The "reusable" space shuttle SRBs cost more than the whole SpaceX rocket just to refurbish. Still less crazy than ULA's plan for their new rocket: Attachment 237850 Also their new upper stage could use a piston engine for electrical power/restarting. |

Attachment 237849 Problem is those RL-10s cost $40 million a piece right now. |
