Addressing Mori, Captain Noda continues: "The housing area will appear to be a prison camp—for special prisoners. Its existence may be known to some on the outside—the local people will see trucks going in and out along the road and will guess as much." Turning to Goto Dengo, he says: "The existence of the Special Security Zone, however, will be totally unknown to the outside world. Your work will proceed under the cover of the jungle, which is extraordinarily dense here. It will be invisible to the enemy’s observation planes."
