The space capsule's first crewed flight has experienced five failures of its 28 manoeuvring thrusters, five leaks of helium and a slow-moving propellant valve that signal unfixed issues from past flights.
The Dragon capsule had to successfully complete both an in flight abort test and several uncrewed trips to the ISS before NASA trusted it to carry astronauts, the Starliner skipped both.
