Isn't 9/11 and especially Pearl Harbour more like war documentaries? As disaster is something that happens more accidentally, unintentionally. And in both cases, those were surely intentional.
I don't watch that much disaster documentaries, but others yes. It is hard to name those, as most don't have English name.
But producer of one good war documentary about Hitler and one about D-day:
Spiegel TV
EDIT:
Chronicle of the Third Reich
D-Day
