The really scary part of that F-104 procedure to me is steps 5 and subsequent, with a big WARNING label. The gear are not extended until AFTER the flare is begun, at which point the aircraft will decelerate and descend at a prodigious rate. And that NOTE at the bottom right would be mighty worrisome to me as a pilot. And with a downward firing ejection seat, its not like the pilot could change his mind and get out after Low Key. Low Key was his do-or-die final checkpoint. After that he was well and truly committed to the landing. And perhaps even then, maybe a quick final roll to inverted would be his best chance of surviving an ejection at Low Key.
