Goff <jongoff@xxxxxxxxx> made the phosphor on my monitor glow in such
a way as to indicate that:
Rand,
Actually, Kistler has the option to do either, if they have a
down-range landing site for the first stage.
Exactly, a vehicle designed to handle Option 2 should be
able to do Option 3 if there is a suitable downrange site.
It's rather impressive how much extra payload that can
mean for a vehicle. At least according to some BOTE
work I did on the concept, it can be as much as a factor
of 2-3x more payload depending on the details.
Yes, it's a function of both relative stage Isps and staging velocity.
