Falcon Heavy side boosters landed successfully today. Throttable (liquid) RP-1/LOX fueled-boosters capable of recovery and reusability, with 140000lbs payload to low earth orbit in the heavy profile . . . may have to re-evaluate my opinion of Musk as a rent seeker. This is a major step forward for launch systems, huge potential to drive down launch prices.
