I saw that too... right over my house! I watched it all the way down on final until it was out of sight. Wife and I thought it was very strange because AFAIK, C-130's are generally restricted to a 40 degree bank by AF regulations, and when not involved in combat (including forest-fire combat), there is really no reason to make more than a 30 degree bank at any time.
I concluded to myself that the pilot had just missed his turn for final and had to really bank hard to keep his approach.
Prayers to the crew and their families.
