P.S. My very first assignment at Boeing was to determine the size of that jackscrew needed to carry the load. I panicked, and went to my lead engineer. He laughed, and said "you know how to do column buckling calculations, right?" I said yes, and he said go to it.

After 3 years of working on the gearbox I knew everything there was to know about it, including all the failure modes anyone could think of. I was also fortunate to have a couple of Boeing's best engineers mentoring me.

It's redundant.
