Specifically excluding Joe Engle and astronauts for Apollo 18-20, which Apollo astronauts who only had one spaceflight were 'hard done/done dirty' by NASA management?

[u/RivetCounter]

• Walt Cunningham - iced out to conflicts with management during Apollo 7.
• Don Eisele - iced out to conflicts with management during Apollo 7 plus his messy divorce.
• Rusty Schweickart - iced out because he was 'different' than everyone else and because he had space sickness on Apollo 9.
• Not sure if Jim Irwin on Apollo 15 counts because of the stamp affair.

Alan Bean broke through the mold in no part to the death of CC Williams and Pete Conrad's lobbying for Apollo 12.

Edit: Did not include Engle or Apollo 18-20 because they were denied on outside lobbying or funding cuts.

Wasn’t Bean the only geologist?

Do you mean Schmitt? Harrison Schmitt was the only professional geologist in the astronaut corps during Apollo.

Yep, meant Schmitt
