had up in the air, the crew that was up there was able to spot a campsite or a remote camp area that appeared to have two people. as we were able to watch more closely, the fbi teams and the teams that were watching confirmed that they believed this was dimaggio and hannah there on the ground. once we had that information, the hostage rescue teams moved in. there was challenges with getting the teams close enough to the camp but they moved in as closely as possible to get hannah rescued immediately. >> how long did they have to hike? i mean, this was such a remote area. they couldn't drive anywhere close to the campsite, right? >> absolutely not. there is no vehicle traffic allowed within this protected wilderness area and the second challenge was the terrain. so it is not flat land. it's very steep, rugged terrain.
