Its launch officer, a lieutenant, did not acknowledge the authority of the senior field officer—i.e. Capt. Bassett—to override the now-repeated order of the major. The second launch officer at that site reported to Bassett that the lieutenant had ordered his crew to proceed with the launch of its missiles! Bassett immediately ordered the other launch officer, as Bordne remembers it, “to send two airmen over with weapons and shoot the [lieutenant] if he tries to launch without [either] verbal authorization from the ‘senior officer in the field’ or the upgrade to DEFCON 1 by Missile Operations Center.” About 30 yards of underground tunnel separated the two Launch Control Centers.
