If the mission was as it looked on the surface then the ops can be faulted for not destroying the equipment. If Pueblo was like other such units, at least like the RC135s in the AF, there were preplaced thermite charges that would have reduced the equipment to slag and cinders quickly if deployed.The failure to do that gave rise to suspicions that Pueblo was meant to be captured- see #31.
Yong-Son command center was thusly wired.
