Although the synchronous landing of the Falcon Heavy side boosters looks impressive, they seem to have traveled a long way back to the landing zones.

How does this compare with Falcon 9 launches with land landing?

Would it have been more efficient in this case to land the side boosters on additional droneships?

I'm interested in whether the amount of droneships was a bottleneck here, or if the way it was done was actually the best option.

Also, are there any plans known for possible multi-droneship missions?

    $\begingroup$ When Red Dragon was on the schedule, it was going to land the side boosters on droneships and expend the center core. Moot point now, though. $\endgroup$ – DylanSp Feb 6 '18 at 21:56

  • $\begingroup$ Thing is, if the side boosters land in the sea, you kind of have to expand the central core since it'll separate even further away $\endgroup$ – Antzi Feb 26 '18 at 5:27

Currently SpaceX has only one drone ship in the Atlantic, Of Course I Still Love You, so it wasn't an option. As far as I know, they aren't planning to build more; their goal is to do as many return-to-launch-site (RTLS) landings as possible in the future.

Landing all three on drone ships would allow them to expend more fuel in boosting, increasing the potential payload of a Falcon Heavy launch, but it would add several days of sea travel to the turnaround time of a booster.
