Yikes. This is scary, and not good. One reason why it is not good is because lets say they try to do it again, and the craft suffers a fuel leak, but this time, there could be a risk of a bigger fuel leak. Its crash landing won't just be any crash landing, But the craft might be damaged, that it might not be able to go on missions, and it might be in a repairing state for some while. Gladly, It was damaged that much, and the debris didn't reach the lower atmosphere, which is good. Hopefully next time, this doesn't happen again!
