In 1985, I rode in a CH-53E Super Stallion over a small fire near Saddleback. We were 1,000 feet AGL, and we still got bounced around a bit.
400-500 feet AGL in a much lighter Seahawk over the Cedar Canyon fire would be...ahem...an experience.
It'd be a rodeo in the lighter helo, that's for sure.
Back to work for me.
