Default Were liquid boosters on Shuttle ever realistic?

According to Wikipedia
(https://en.wikipedia.org/wiki/Falcon_9#Notable_flights, heading
"Relaunch of previously-flown first stages") there have so far been
*three* reflights of Falcon 9 boosters, not one. All successful, and all
relanded the booster, again.


Thank for clarification.

Stll not the 15 or so flight another poster claimed.


No one claimed 15 REflights. We've been pointing out 15 flights, with 4
more definitely planned. That's a higher rate than pretty much anyone
booster.
This for a system that's still relatively new. Oh and Boeing moved an X-37B
flight to Falcon 9 off of one of their own ULA boosters.

And they've shown an ability to reschedule payloads as things change. If
nothing else, the ability to stack and destack in under 2 weeks (I think
it's actually just a few days) is a huge improvement over existing
launchers.


They note that the the first reflight resulted in the booster, despite
landing fine, was retired. I would assume SpaceX wants to figure out how
many times boosters can be re-used, and retiring after only 2 launches
isn't that great.


Sure it is. First it's historical. Secondly you move in incremental steps.

But this is another example of being too early to draw conclusions on
just how reusable they will be.


No, you keep making assumptions about what most of us think.
