Agreed his technique probably kept the body count down for sure but he was not the first to do that in a DC-10 with control problems..That honor goes to Capt Bryce McCormick in an AA DC-10 in 1972 over Windsor when he lost the bulk cargo door and decompression and floor collapse left his a/c with minimal control. He used asymmetric engine thrust to maintain control. Not as dire as UAL 232 but still great airmanship.
