 You know, you have to keep in mind that this is the first piloted flight of the Starliner. They've never had it up with people during a full-up mission. And so they're really kind of trying to wring it out. They think the thrusters will actually work fine. They hot-fired those thrusters that failed later in the flight after it was docked at the space station. They all worked fine, except for one that apparently has actually failed.
