Only a blind person coldn't see, that the tiles based shield is well "fried" !!! In best case scenario they could push it to about 70% reentry success with mandatory required complete refurbishment of the entire shield after each reentry. People on board is 100% out of question with this mildly said POOR factor of safety design. The tiles based shield concept is 100% doomed, if the goals are rapid reusability and human rated vehicle.
