I suspect planes are expensive and they ran out of money. Band of Brothers was a 13 episode order, until HBO realised how much each episode cost.

Orloff wrote Day of Days, which was mostly excellent with a small amount of unnecessary voice over, and Why We Fight, which is probably my least favourite, but I feel like he did the best he could given the topic.

Day of Days has one of the best shorthand character introduction scenes I've ever seen, which I included in my top three favourite moments of the entire show.

I don't think he worked on The Pacific, at least not as a writer.
