Question about Apollo 9 and astronaut Russell „Rusty” Schweickart.

[Pawelk198604]

I heard that he was bumped from crew rotation was because he suffered space sickens, that was official reason, but unofficial was because Alan Shepard return to flight status and want his spot on crew rotation for himself  (at least what i heard  )

Alan Shepard made multiple attempts to return to flight readiness status. Granted he never intended to leave the crew cycle. He only did after he was diagnosed with Minere's Disease (butchered the spelling). He was the original commander of Apollo 13 before his ear infection flared up bumping Jim Lovell and his crew to the prime crew for 13. He launched aboard Apollo 14 as Commander. Only thanks to an experimental (at the time) surgery to drain the excess fluid from the inner ear.

That said, as to 9, I'm uncertain. From what I know, it was pretty concrete. However I admit to not being as certain as I could be and will spend some time looking into this.

According to a book and to wiki, Shepard was not the original Apollo-13 commander.
He had been commissioned (due to Meniere's disease) being a commander candidate for Gemini-3.
Later he became a chief of Astronaut Office and in this status had nominated himself to A-13.

Originally A-13 commander would be McDivitt. He was not happy to become Shepard's co-pilot (as Shepard had just one suborbital flight, while McDivitt had already piloted G-4 and A-9.), and rejected this idea.

Another potential candidate, Cooper (who had already piloted MA-9 and G-5, and was being trained for A-10 and A-13), also was unhappy with this and (when Shepard declared to Mitchell and Roosa that they will be A-13 crew) leaved the Apollo project slamming the door.

After this, Cernan disliked the idea to be a co-pilot for Young in a backup crew (only a chief pilot) and was replaced by Duke.

And then Slayton decided that Shepard can't finish his training for A-13 in time and postponed its crew flight to A-14.
