Actually, the whole report is a bit of a horror story. I think we were all aware of most, if not all, of those issues, but seeing them all listed together and the analysis of the risks of each is, frankly, shocking.
What I haven't quite got my head around yet is the reality of the future timeline. The effect of current problems and change of effort on probable dates for various milestones is well described, but the complexity of the way so many threads interact makes it hard to see exactly where the risks in one thread affect the others, which affect others, etc.
It feels like a house of cards that already has major flaws in the lower layers.
