So much for “re-usable” capsules, huh?
...
Well, we don’t know the reason for the explosion, so that question can’t be answered yet.
A few weeks ago I read a Musk tweet saying that the crew capsules are so expensive to refurbish, they are considering building a new one each time.
When you consider the down list that most airliners actively fly with (taking advantage of redundant systems) you’d have to wonder why they’d even attempt a re-usable crew capsule. It’s not like they can afford the space or weight for a 3rd backup of this or that.
