The Okinawa missiles of October
When the missiles' readiness was raised to DEFCON 2, the crews had been informed that there would be no further such tests. So this time, when the first portion of the code matched, Bordne’s crew was instantly alarmed and, indeed, the second part, for the first time ever, also matched.
At this point, the launch officer of Bordne's crew, Capt. William Bassett, had clearance, to open his pouch. If the code in the pouch matched the third part of the code that had been radioed, the captain was instructed to open an envelope in the pouch that contained targeting information and launch keys. Bordne says all the codes matched, authenticating the instruction to launch all the crew’s missiles. Since the mid-shift broadcast was transmitted by radio to all eight crews, Capt. Bassett, as the senior field officer on that shift, began exercising leadership, on the presumption that the other seven crews on Okinawa had received the order as well, Bordne proudly told me during a three-hour interview conducted in May 2015. He also allowed me to read the chapter on this incident in his unpublished memoir, and I have exchanged more than 50 emails with him to make sure I understood his account of the incident.
