four crew members, ordinary people, not the usual astronauts who have had years and years of training. it was billionaire businessman jared isaacman who paid for the privilege of going up into space. once they landed, after the splashdown, he said it had been a heck of a ride and he said it was just the beginning. he helped the three other crew members and paid for them to go on board. a geoscientist, a us air force veteran and a woman called hayley who was treated for bone cancer when she was a child. she has actually gone back to work at the hospital that cured her cancer. she was seen as an inspirational person, someone who deserved this chance to go up into space. that�*s why it was so different, we are not talking about professionals, amateur astronauts known as space tourists. quite a cast list. we have covered a number of high—profile flights into space recently, but what did this one achieve?
