Last night about 10 miles north of Peterson, we saw a MAFF C-130 make too hard a turn and head right back. He was at a very low altitude and made about an 80 degree bank from what I could tell. When I flew on C-130s we weren't allowed to bank that hard normally, especially at that low an altitude. I was pretty alarmed that something had happened to it, and now to hear this, it sucks.
