I guess I summarize things different than others, but at the 32:00 minute mark, he talks about what he was actually scared about:
NASA is essentially, a business (my addition) -- that does not know how to communicate. The left hand very much does not know what the right hand is doing. He brings up a fantastic example of how many rockets are required for a particular phase of a mission and showed how multiple people gave different answers without even realizing their launch date is set in stone.
In essence, issues abound.
