re: 17th astronauts selection fates
Suni is below right in that portrait of her selection.
Center left below, there is Patricia Hilliard.
She'll never go to space because in 2001, she was in a plane (as a passenger) that crashed (she was not then flying for NASA) and she got out of the plane but was so severely burned, she died 3 days later.
There are other group portraits of astronauts where it is troubling how different their fates turned out to be.
